Automatic recognition of contact surfaces

Hello,

 

I am performing a structural simulation in Simlab. I have imported the CAD model and created the mesh. But it is an assembly, and I have to define the contacts between parts. Is there in Simlab a command to automatize this task? For example when you import in Simsolid it recognizes contacts automatically and show them. All contacts in my model are bonded contacts, how can I define it? Regards.

    We dont have auto contact recognition during import like SimSolid.Did you try auto contact creation in SimLab ?

    Hi,

     

    Attached video is a simple structural simulation video. In this video, go to 0.59 sec. It will show you how to create auto contact creation for an assembly.

     

    Thanks & Regards,

    Thank you very much for your good response.

     

    I have defined a model, but now I have the next error and I can't continue with simulation:

     

    ************************************************************************

    Errors reported during program execution

     

    hwsolver.mesg output from the solver:

    ==============================

     

    *** PROGRAM STOPPED: ERRORS DURING ELEMENT QUALITY CHECK.

     

    1- I want to check the elements that give me this error. How can I find them?

     

    2- Also I want to know about the posibility to undo these checks: If I know that the interest region is meshed with good quality, is it possible in Simlab to undo this?

     

    Thank you.
