Thanks for the reply, the strucutre has been EM simulated in HFSS where the meshing etc.. is working fine. I now want to perform the static structrual analysis of the structure in Workbench. In workbench the meshing seems to be failing despite trying workarounds to it hence I was thinking of resung the meshin generated by HFSS in workbench for mechanical analysis. 

On a side note is it also possible to peform Mechnical stress/strain analysis in the AEDT envirobment itself ?
