    Using CBUSH Elements in GAP Element Connections

    Hi Diego! Thank your support on this! 1. I originally had a stiffness value of around 1E10, but I noticed after iterating when running the analysis in BAILOUT, a stiffness value closer to 5.0E20 caused the VM stress to converge on values similar to the plate-on-plate contact analysis. My last...

    Using CBUSH Elements in GAP Element Connections

    Hello, I have a mass element attached to an RBE3 connected to surface #1, and surface #1 is connected to surface #2 via gap elements. Because I’m not concerned about the stress results from surface #1 and just care about the stiffness it imparts onto surface #2, I tried to replace surface #1...
