I would have to take residual stress in steel beams, initial imperfections and material non linearity into account. (GMNIA) . I would like to decide between RFEM and ANSYS.
I need to perform a parametric study on lateral torsional buckling of beams(for a system like in the picture), So please help me decide which software would be suitable and also let me know if it is possible to model buckling of beams with restraints (restraints from cross beam)
The ease of your analysis depends on the performance of your computer. As far as Ansys is concerned, it is one of the best analysis software available in the market.
Buckling analysis is quite useful and easy in Ansys. You follow the same steps as you do in Structural analysis and an almost relevant buckling result is your output.
