I am trying to run a simulation on a frame that was created using weldments, however this frame must have tabs on it so that an assembly can be constructed out of it with suspension which I would also like to run a simulation to see where the high/low stress points are. Any help would be greatly appreciated and I will attach the frame with the tabs that I have completed thus far. Now this is a rework of what I had already completed, as I had already made all the parts and assembly for the final product, however I kept getting error and then SW would crash on me when I would try to mesh everything together. So I am trying to troubleshoot my way through every part to try to understand what is going on, and I can not seem to understand why nothing I am trying is seeming to work?
