I am currently trying to perform modal analysis on a surface model of a bicycle frame. I know how to perform the procedure, however ANSYS does not come up with any results when I execute the function.

I built the CAD model using solidworks, and I made sure that there were no intersecting tubes by trimming the overlapping area using the 'surface trim' tool.

I experimented a bit and got the analysis to work when I suppressed all but one tube at a time, but as soon as I try to analyze more than one segment at a time nothing comes up. My guess is that there is a problem at the joints, but I'm unsure how to mend this issue.

I've attached a photo of the model and the negative analysis results.
