One of the most user friendly is RISA 3-D. RISA is primarily a structural analysis program. Autodesk has some FEA software (i.e, inventor, etc.), but had discontinued some of the FEA software . If you want FEA, many moons ago I used FEMAP & MSC/NASTRAN. FEMAP may have been pre- and post processing software for NASTRAN. Bentley has structural analysis and FEA software subscriptions. I believe STRUDL is still out there; heard of it but do not recall ever using it.
I still have my desktop versions of RISA 3-D from way back that did not require subscriptions. I simply have to do the design calculations.
Blodgett is an excellent source. I have duct tape holding my Blodgett together.
