Hi everybody, I'm new on solidWorks simulation, so maybe I did something wrong, but here is my problem: I have to do a static study of a frame which is composed on beams and four metal sheets with gussets. the structure will be supported by the four metal sheets. I kept global contact as default ( bonded) and I created contact set between the metal sheets, gussets and the beams on which the sheets are welded. I fixed the sheets and put the load on the structure: gravity + weight supposed to be supported by the structure. When I run the analysis after meshing, this message appears: "improper or no target define for contact element XXXX" Could someone help? I'm lost!!
