Matrix solver exception: could not apply displacements because the mesh would become invalid
I try to perform a EM-thermal-stess analysis in Workbench 19v2 of a simple microstrip line section and use the displacement data from Ansys Mechanical to simulate the altered behavior of my microwave element. The maximum displacement I get from the structural analysis is 25 um. However, feeding this data to HFSS results in invalid mesh error, as follows:
"Solving adaptive frequency …, proces hf3d error: Matrix solver exception: Could not apply all displacements because the mesh would become invalid".
Any suggestions how to cope with this problem? My EM setup is: 0.005 max delta S, max 15 passes with basis function of zeroth order.
