Meshing Issues with Imported model

I imported a frame model(Assembly) using livelink for ProE and saved the model in COMSOL 4.1. I'm trying to run a bacis static load study on this frame but while Meshing it gives me errors which dont let me run the study. the Error say Free tetrahedan and uder that there are multiple errors and warnings that say mesh cannot be created. Can someone please help me solve this issue.... and also what would be the best way to import PRO-E complex models/large assemblies.
Thanks in advance

You need to post your file if you want specific help. Too hard to diagnose a problem/recommend a solution just by a description sometimes.

Would clearing the solution reduce the file size? (File>Clear solutions)
Yes clear the solutions/results and then your file size will drop.

My suggestions are this:
1) Draw one piece of your structure in your CAD package and then import it in to comsol. Then manually draw in the same thing using comsol and compare the meshes. Repeat for two elements (and etc) and see if you can tell how the CAD tool is affecting the mesh. Make sure you draw things that intersect so that you can see how the mesh is being generated. While I would like to tell you that you can use the geometry you have, at this point it is beyond my mesh abilities to fix this or suggest things to do. One thing you can try is go into the CAD defeaturing and repair (right click geometry node) and see if removing elements help. This is trial and error on your part.
2) Another option is to draw this in the comsol gui. Yeah, I know, you paid for the livelink and it should work. If it was me, I would try and do this. You are limited what you can do when you import in other non-native geometries. I can see why you would want to import this but it is what it is.
3) If you are on paid support, send the file in and see if they can work it out.
4) If you have any symmetry in your problem, exploit it. It will simplify your life more.
Someone else may be able to help you here that knows some tricks.
