problema simulation xpress

[pironman]

I am making the frame of a liquid trek on solidworks, and performing the simulation wizard simulation of simulationxpress, it gives me unsuccessful mesh problems.
I tried to make mesh rougher, but always trouble, and always on the fittings.
So I tried to eliminate the fittings, and it gives me problems on cuts-extrusions.
I attach the file with the frame, I can't understand what the problem is!

Thank you.

p.s. the upper tube of the frame I tried to realize it also, rather than for extrusion by revolution of a rectangle, by extrusion of a circle, putting the option "up to the body" and selecting the body against which the tube must end, but still gives me problems in that extrusion, remove the edges

Have you tried to run a mesh based on curvature?
Obviously the normal mesh cannot generate itself, then go to refine the "mesh size" in the points you feel strategic with a "mesh control application".

I found the problem, even if I had to make almost everything happen again!
between the steering column and the bottom tube of the frame was a very small edge, due to the extrusion with loft that I accidentally finished a moment before, which gave problems.
I stretched that stretch and it went well, then it still gave me problems with the fittings with radius of 5 mm, I made them with radius of 8-10 mm and it went well, boh go to understand why
