What is the difference between optistruct (load step type- geometric nonlinear dynamic explicit analysis or multibody dynamic analysis) and radioss (multibody dynamic analysis).?
Which analysis is most suitable.?
Hi Dhananjay,
Altair® OptiStruct® is an industry proven, modern structural analysis solver for linear and non-linear structural problems under static and dynamic loadings. It is the market-leading solution for structural design and optimization.
Finite element solutions via OptiStruct include: • Linear static analysis • Non-linear implicit quasi-static analysis • Linear buckling analysis • Normal modes analysis • Complex eigenvalue analysis • Frequency response analysis • Random response analysis • Linear transient response analysis • Geometric non-linear explicit and implicit analysis
• Dynamics analysis • Static and quasi-static analysis....etc

The solver is selected based on the applications. For explicit dynamic cases always select RADIOSS solver. Typical examples are crash analysis. impact analysis. drop test....etc
For implicit solutions select OptiStruct solver.
