COMSOL Multiphysics

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.

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.
