hi,
i really have no idea which solver should i use. some say its better to use direct sparse on large displacement problems.
can anybody tell me all the features as well as DO's and DONT's with those.
thanks

for Static Problems:
we can use Direct Sparse solver, and the FFE solver.
1. we can Use the FFE solver for large and very large problems (problems with over 300,000 DOF).
2.Use the Direct Sparse solver for small and medium problems (problems with 100,000 to 300,000 DOF).
3. Use the Direct Sparse solver for assembly problems with contact, especially
when you turn on the friction effects.
4. Use the Direct Sparse solver when solving assemblies of parts with widely
different material properties.
