Using SW 2009 with Simulation Pro I get some very strange results.
I am modelling a very simple bicycle frame under loads. I have designed it using weldment structural members and meshed using beam meshing. My results have been fairly strange.
The default stress plot is STRMAX- Worst Case stress. This shows an accurate/expected reading of around 40MPa under the load I am subjecting it to. But when I list the results and get the von Mises stress table, my maximum vM stress is a measly 900N/m^2 or so.
My question is... whats wrong? Why such the massive difference between max worst case versus max von Mises?
A second question is, is there any way to refine beam meshing? I only have the option to 'create mesh' with an all beam component. Cheers for any help,
Robert
