It has more than 25000 components that are different and complex in design. In following briefly describe the each packages capability, features and some key features each software package offer. Siemens NX and CATIA are some of the high-end CAD/CAE/CAM software packages currently available in the market. The graphics and selection functions for loads and constraints could do with better graphics for added clarity.While some programs are mid-range levels, others are high-end CAD. Establishing contact definition between parts is cumbersome. If a run fails, not much information is given, and you have to sift through a long, cumbersome results file. SIM file run times can be a bit slow at times. Before NX CAE, I was an I-DEAS FEA user, and find it much more modern than that. Meshing is quite quick compared to other software. 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. The FEM contains the mesh, and the SIM contains the loads and constraints.
You can tune it and remove features without affecting your original part. The idealized part is nice because it is linked to your CAD part, but it's just a representation of it.
NX8 CAE is structured with three files: your Idealized Part, your FEM, and your SIM. 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. Correlation between real-world failures and NX8 CAE was good, so there was confidence in the designs released. 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. The Mesher is quick and there many options.
Comments: Using NX8 CAE allowed me to load and constrain CAD models and assemblies, to know how much stress and deflection the designs were seeing.
