SolidWorks does have limited FEA in the form of SimulationXpress. However, the limited choices in loads and constraints can make it difficult to achieve acceptable results.
If the frame is an assembly Simulation Xpress will not work.
From the help file:
"SimulationXpress supports the analysis of a single, solid body. It does not support assemblies, multibody parts, or surface bodies."
