NX 8 CAE

It is a useful software in mechanical engineering

Vorteile:

The software allows modeling, simulation and design for many topics in mechanical engineering and others fileds

Nachteile:

It is an expensive software, the technical support is late. This require a previous knowledge for use it.

Siemens NX8 is a great way to analyze NX CAD models or assemblies for stress and deflection

Kommentare: Using NX8 CAE allowed me to load and constrain CAD models and assemblies, to know how much stress and deflection the designs were seeing. The Mesher is quick and there many options. Manually defining welds with connector meshes is actually efficient because everything is known and defined by the user, whereas auto weld/connectors may overconstrain a part and produce inaccurate results. Correlation between real-world failures and NX8 CAE was good, so there was confidence in the designs released. It is very thorough, capable software, but the price tag is high and Siemens have to realize that companies like SimSolid are producing equally capable software, for similar applications, at a fraction of the price, hence recommending is about neutral.

Vorteile:

NX8 CAE is structured with three files: your Idealized Part, your FEM , and your SIM. The idealized part is nice because it is linked to your CAD part, but it's just a representation of it. You can tune it and remove features without affecting your original part. The FEM contains the mesh, and the SIM contains the loads and constraints. Not all analysis software compartmentalizes everything this way, but I think it's a good job and keeps things organized, which not all software does. Meshing is quite quick compared to other software. Before NX CAE, I was an I-DEAS FEA user, and find it much more modern than that.

Nachteile:

SIM file run times can be a bit slow at times. If a run fails, not much information is given, and you have to sift through a long, cumbersome results file. Establishing contact definition between parts is cumbersome. The graphics and selection functions for loads and constraints could do with better graphics for added clarity.

A one-stop shop for CAE

Kommentare: Our customers that came from other CAD tools were happy to find in NX a solid CAD interface, and all the other functions (coatings, validation tools, logic editor..) have been a helpful addition.

Vorteile:

The sheer number of CAE features, their usefulness, and the overall completeness, especially in the lastest versions

Nachteile:

The learning curve is a bit steep. While it provides tons of features, integrating them with some more specific tools can be tricky.

make it user friendly

Kommentare: Not easy to find the a way to remove errors, complex structure, all options are not available at one location.
Not at all user friendly software.

Vorteile:

not much to tell, measuring , .prt .fem .sim

Nachteile:

node association, enable FEM update(again have re associate the nodes -- causing errors).

NX CAD-CAM-CAE greatest software

Kommentare: I found Nx as one of the most complete CAE software in market. It has features that compete hand on hand with the rest of them, but Nx interface was friendlier.

Vorteile:

I love the freindly interface compared with others, that are similars, I found Nx´s easier to understand.

Nachteile:

I used to use Nx to learn mechanical design at school, with my university´s licence. So when i graduated I couldnt use it any more. And I dont like that its very expensive to regular users.
