COMSOL Multiphysics Erfahrungen

The software clearly makes multiple coupled physics interactions easy to simulate

Kommentare: Have solved engineering problems for clients who were looking to launch new products. Cut down development cycle times and cost of prototype building in multiple cases. Overally, the cost of entry is high, but once it is set up and in use the rewards justify the initial investment for engineering research firms.

Vorteile:

They have been a pioneering software in the multiphysics area and conduct very good training programs to get students and users off to a good start. The interface is set up to be used in a methodical manner but can also be flexible. Options for both standalone as well as volume licensing are available so organizations can share licenses among multiple users. The benefits of using this for applicaiton development is very high in engineering and COMSOL's knowledgeable engineers are available for discussion and support.

Nachteile:

Cost is on the high end. The set up and management needs some dedicated backend IT folks for volume licensing

COMSOL Multiphysics: A Powerful Tool with Some Limitations

Kommentare: Overall, I would highly recommend COMSOL Multiphysics to anyone in need of a powerful, yet user-friendly simulation software. Its well-described equations and easy-to-use models make it a valuable asset for any project.Despite these limitations, I still believe that COMSOL Multiphysics is a powerful and valuable tool for simulating complex systems. Its ease of use and versatility make it a valuable asset for engineers, researchers, and scientists working in a variety of fields. However, it's important to be aware of its limitations in order to make the most of the software's capabilities.

Vorteile:

I have been using COMSOL Multiphysics for some time now, and I am very impressed with its capabilities. As someone who regularly deals with problems of solid acoustic interaction, I have found the Pressure Acoustics Module to be particularly useful.One of the things I appreciate most about COMSOL Multiphysics is how well the equations are described. The software is very user-friendly, and I have found that the models are easy to set up, even for someone who is relatively new to the program.The Pressure Acoustics Module is especially helpful for simulating acoustic pressure waves in fluids and solids. It allows for accurate modeling of complex systems, including the interaction between sound waves and materials.Another advantage of using COMSOL Multiphysics is its versatility. The software is capable of modeling a wide range of physical phenomena, including electromagnetics, structural mechanics, and fluid dynamics, among others. This makes it a valuable tool for engineers, researchers, and scientists working in a variety of fields.

Nachteile:

While I have found COMSOL Multiphysics to be a valuable tool for simulating complex systems, there are some limitations and drawbacks to be aware of.One challenge I have encountered is setting up parallel computing. While the software does support parallel computing, it can be difficult to configure, and it can be hard to tell whether the software is actually running in parallel in a cluster setup. This can be frustrating for users who are looking to optimize their simulations.Another limitation I have encountered is that some modules have limitations that are not well described in the manual. For example, I have found it challenging to create an absorbing PML for a time-domain simulation. While it is possible to do so, the process can be complicated and may require additional research or support.Finally, I have also found that customer service can sometimes take longer to reply than I would like. While the support team is generally helpful and responsive, there have been instances where I have had to wait several days for a response to my inquiry.

COMSOL review

Kommentare: Strong support for custom physics and modules enables tailored simulations for specific optical phenomena.

Vorteile:

I'm an optical engineer and it allows me integration of optical, mechanical, thermal, and other physical simulations, beneficial for complex multiphysics systems. COMSOL's user-friendly interface simplifies geometry creation and meshing, speeding up the design process.

Nachteile:

Optical simulations may lack the specialized features of dedicated optical software like ZEMAX or CODE V.

Could be better

Diverse options for a chemical engineer to apply to different areas of his/her work.

Nachteile:

Could be more user-friendly with broader database.

A great software for solving finite element analysis

Kommentare: If anyone wants to get the best out of this software, it is highly recommended to go through intensive training provided by COMSOL, it is worth. This software is able to do real-world complex simulations, and in my experience, it can often become challenging to even deploy the full potential this software can provide because we are not even aware what can be done with this. It is better to run complex 3D simulations on a powerful workstation or cluster computer, as COMSOL is intensive memory consuming software.

Vorteile:

I have been using this software for the past 10 years and have witnessed the growth of this software. COMSOL is one of the best software to date for Multiphysics applications. Some of the distinct advantages I have experienced are: 1. It is very easy to learn provided one must know the underlying theory behind the simulation, i.e. equations and empirical relations one has to consider for a specific problem. 2. Documentation is easily accessible, blog posts and COMSOL user community is very helpful and growing rapidly. Additionally, they have the best and easily accessible support staff able to answer any relevant questions. 3. GUI and post-processing visualizations are remarkable. 4. Highly capable multiphysics software with great ease of use and customizable for a wide range of applications and real-world scenarios. Very easy and simple coupling between physics modules. Simulations are easy to set up which involves multiphysics. 5. CAD modeling is unbeatable. Complex geometries can be solved with an ease that are extremely difficult with other software.

Nachteile:

COMSOL has a lot of cons and listing all of them is impossible. But some of them which I frequently have to deal with are: 1. It is computationally intensive software, needs a lot of memory and processing power. 2. It is slow because many post-processing steps equations are solved simultaneously and when actual post-processing is done, it just extracts the results from the solver. This makes the solution extremely slow if complex geometries are involved. 3. Due to the finite element approach, the convergence of the solution can often become challenging. 4. Because of the meshing issues for complex geometries, the converged solution can be difficult to trust. Also, apart from the built-in functions for physics, it can be really hard to figure out how to numerically solve pure and applied math problems that don't fit neatly in their packages.

Excellent and useful software package for analysis and resolution by finite elements.

Vorteile:

Very versatile for the study of coupled or multiphysical phenomena, also offering a very good interface with Matlab, for example. Even more versatile is the fact that the simulation packages that make up the program are multiplatform, so they can run in Windows environments, such as Mac and Linux, for example, which for a teacher, as in my case, gives me wide freedom for its pedagogical use among students. Another intrinsic property of importance is the fact that the user can define at pleasure, practically the number of local coordinate systems that he wishes, being able to work simultaneously in 3D, 2D and 1D.

Nachteile:

The amount of memory that is required to run a simulation is large and the execution time can be quite long for an individual simulation. However, if the Comsol Mutiphysics is used with a floating network license it is possible to use the client-server operation mode to access the remote calculation resources to solve large models, while continuing to use the graphics card in a machine local for the visualization of the graphics. This mode of operation can generate many advantages above all in terms of obtaining faster and more efficient results when working with models where intrinsically is being solved over and over again, a large system of equations.

This is one of the best finite element modelling softwares that I have worked with.

Kommentare: I learnt a lot in general about how finite element modelling works. I worked with a lot of different element types, mesh sizes to see how it affects my problem.

Vorteile:

The best thing about this software is the freedom that it offers the user to select the physics of problem and the kind of dimensional space the user is working with. The user can make the geometry with ease and mesh it according to his or her needs. There are a lot of options available for post processing data which helps the user to see convergence of various mesh sizes and make sure that their model is an accurate representation of the true problem. The user can combine various solution sets and extract data for further processing.

Nachteile:

There is not a good library for this software. One has to browse through forums online if they get stuck at some point with their problem.

COMSOL Multiphysics is the tool of choice for my research needs

Kommentare: COMSOL has been a daily workhorse for my Mass transfer modeling needs.

Vorteile:

COMSOL has allowed me to model many mass transfer phenomena that are difficult to do by hand or with softwares such as Matlab or Mathcad. It has a nice step-by-step approach to begin my modeling, allowing me to pick different physics and variables with ease. The online help and tutorials are plentiful and useful.

Nachteile:

Sometimes, even when attempting to save a report as a word or text document, COMSOL will save it as a different file type until the second try.

Academic user

Vorteile:

wide range of application areas from physics to engineering User friendly

Nachteile:

To achieve accurate simulations in COMSOL, it's crucial to find an optimal mesh for your specific model and geometry. Adjusting mesh parameters and refining is difficult

Broad but not particularly sharp

Vorteile:

You can do a lot, covers many different analysis types. Great if you need multiphysics. Can tie to matlab

Nachteile:

Not so great for specific analysis like structural analysis. No explicit modelling. Lacks some refinement in tools. I’d have to make a lot of custom shortcuts to bring it up to par with other analysis softwares

COMSOL knows all about physics

Kommentare: I simulated a thermal-fluid dynamics coupled problem system with complex and confined geometry. If I was using Code Aster, MATLAB, or open source programs, it would take me a decade coding and choosing the right meshing method. COMSOL, however, got it done in one afternoon. My supervisor was very happy seeing my quick results.

Vorteile:

Since I work in mechanical engineering, I use mostly the finite elements and CFD calculation. COMSOL offers diverse meshing options and knows by heart all laws of classical physics. You almost feel like using a drop-and-drag application, even while simulating complex physics phenomena. And even if you have trouble designing the object, COMSOL customer service is always here to help.

Nachteile:

The cost. Even though I know that it get my money's worth, I am not always using all the functions, therefore a partial subscription would have me save a ton.

COMSOL Simulations

Kommentare: It is expensive. It needs a powerful computer. But it is much better than ANSYS. It also suits more to small scale mechanics like MEMS, etc.

Vorteile:

COMSOL has various modules like MEMS, mechanics, stresses, frequency, magnetism, etc. All of the modules can be seemlessly integrated with the main software. Developing main geometry and running the final study is quite smooth. Various parameters can be controlled within the study. The final results is provided with different color gradient which makes it much easier to visually explain the result to non-tech people. I also liked the variety of materials which COMSOL has got. It is also quite convenient to change different parameters of the materials.

Nachteile:

What I liked least about the software is the computation power it needs. If I run solidmechanics and electromagnetism modules all together with finest meshing, it would take more than 2 hours for my computer to complete the simulation, considering that I have a high end desktop with 16GB RAM and i7 processor. Therefore, it is better to use it from a remote server which is alot more powerful than desktops.
