    Changing pressure BC during solution based on contact region, is it possible?

    Hi The problem you are facing is due to the material model you use. To simulate such problems, you need to use Gasket joint materials. Regards, Desserve Engineering

    Harmonic analysis- base acceleration

    Do you know that a mode superposition method is faster? You try performing modal first and then perform Harmonic. Make sure you extract modes for frequencies upto 2 times of that required in Harmonic and then perform harmonic on modal results. Regards, Desserve Engineering Solutions

    Restart control

    Hi You may generate two load cases. I think first one (moving structure by 0.2mm) should converge easily. The second one wherein there should be non linear contacts, you need to generate manual restart points. I prefer to use equally spaced point generation. Once it is not converging, you may...

    Suggestion for Shell element type for Stainless steel sheet metal part.

    Hi There are few insights: 1) Check to validate whether it is proper to use shell elements for your problem? 2) If yes, then go to mesh and then change "element midside nodes" to "drop" instead of default option of "Program Controlled" and see the results 3) Check whether you've not kept NLGEOM...

    How to have an axial load in modal analysis

    Do a static analysis using an axial load first. Then use the pre stress analysis to calculate modal analysis results. If you use workbench, then add a structural environment using axial load. On the solution tab, right click and then choose "transfer data to new modal analysis" then conduct...

    modelling of contact in harmonic response

    I presume that you must be doing a mode superposition analysis. Modal Analysis doesn't support any non linear contacts and hence you will see them as same. The correct method will be to model the Concrete by applying damping and to model the bars as link elements. You can also try doing a full...

    Thermal stress in piston engine - constrains problem

    Hi I saw your problem and my recommendation will be 1. create a negligible mass element at the pin center and attach the mass element with the surface of hole by means of cerig. After that you can fix the mass element points and then run simulation to see thermal stresses. Regards, Raj...

    Harmonic analysis- base acceleration

    What kind of harmonic load are you applying? Are you looking for a mode superposition analysis or a full harmonic analysis code? I can provide. Thank you
