Differences between HyperMesh and Simlab

Hello All!

Currently I'm making a benchmarking between SimLab and Hypermesh to define which software will fulfill our company needs. Our main analysis performed are mechanical.

I know that Hypermesh is better for shell elements and SimLab for tetra but I want to know the overall differences. From solver compatibility, CAD interpretation, until modeling setup and scripting.

I'm wondering if there is any documentation available for the pros and cons between this two software.

Regards!

    Based on my experience and some users' view, I have some comments below.

    1) Simlab Advantages vs HM

    + When the alloted time for your project is short and your problems are not complicated (Highly nonlinear transient, large assembly), meshing with HyperMesh (especially with shell mesh) is too long. SImlab quick tetra mesh is very effective!

    + Mesh control in Simlab is very nice. It helps you quickly to generate tetra mesh with "Good enough" quality. You can improve mesh quality by mannualy edit if you want

    + Setup analysis is easy (Material/Property, contact, BC)... And you can do multi-physics simulation (Structure, Thermal, CFD, EM) more easily

    + Lower Price --> Good for Small and Medium CAE teams or CAD+CAE engineers.

    2) Simlab Disadvantages vs HM:

    + Simlab does not have CAD engine >> It is difficult to edit geometry. Sometimes, you need to have good native CAD input.

    + Shell Mesh is limitation --> Hard to do Mid Mesh for Plastic parts.

    + Solver cards is not explicit (clear) as HM

    + Solver cards support is not as many as HM.

    + Connectors is limited.

     

    In conclusion, depends on your project and problems, you can decide the right tools.

    For PowerTrain parts, E-Motor, Heavy industry, Simple Solid Drop test, Electronics parts>> Simlab is better.

    But for Automotive Body >> Mainly use Shell >> HM is better.
