Hey guys, My name is Sam and I'm new to this forum. I am more into material engineering as a profession but have used solid works a fair bit over the past years. I am trying to help design a trailer frame for a friend. However I can not get it to mesh at all with a variety of settings. I believe its probably because of my sloppy design since many changes were made during the process however if there is any way to fix this without redoing the whole model id be grateful. I need to run some simulations on the frame to check for stress due to loading. The model is attached below.
