Using different symmetry in different load step

Using different symmetry in different load step

Using different symmetry in different load step

(OP)
Hi, I am doing a static structural analyse in Ansys classic v. 11. The Analyse is nonlinear because of nonlinear material and contact elements.
My model is geometrically symmetry in x and y directions.
The loads in first and second load steps are also symmetry in x and y directions but the loads in third load step are only symmetry in y direction.
Is it possible to analyse the first and second load steps according to symmetry in both directions (to analyse the 1/4 model) and then analyse the third load step according to symmetry only in y direction ( to analyse the half of the model)?

Regards
Jalil
 

RE: Using different symmetry in different load step

yes it is.do your analysis in the first two loadsteps.after that restart your solution that is by using "restart" in the solution control menu.delete the extra symmetry.keep on your analysis

RE: Using different symmetry in different load step

Thank you Omid for your reply.
The first two steps calculate the initial stresses (self weight of the model) and the third step's results depend on them. I have also contact elements.
I want to analyse the first and second load steps with 1/4 of the model and then reflect the geometry to create the symmetry part before to start the third load step. Of course I have to change the B.C. for third load step too.
Is it possible to do that? Thank you very much in advance for your help.

Regards
Jalil
