(OP)
Hi Group,
Question. I just bought a license of Ansys Professional and am having trouble with the "large deflection" solution setting. My VAR's technical guy told me that a professional license may only support geometric nonlinear options for shell elements not solid. Is this right?
I looked at all of the Ansys capibility charts and they do not specify this little detail.
Has anyone delt with this before?
CJ

RE: nonlinear using professional
In workbench I select "large deflection=on" in the solution options...at that point the cells turn yellow and a little red explimation point appears in the solution tree. It will not let me solve.
In the classic enviroment I get this message when I go to solve:
"The SOLID186 option NLGEOM=1 was either not ordered with the ANSYS installation or the appropriate product was not selected for this session..."
Am I using an inappropriate element type for my license? In workbench I dont think you have the option to change the element type, but???
Thanks for the input,
CJ

When I mesh in Workbench an transfer to the ansys classic the default element type is someting called MESH200...what type of element is this?
RE: nonlinear using professional
You can choose different element types in workbench depending on the mesh properties you've specified. For instance, if you have a hex dominant mesh, you can choose either first (reduced) or second (full) order quads (185 or 186) - see the element integration scheme in the details sections of the mesh in workbench. The issue surrounding your NLGEOM message is strange. It appears as though you don't have the licence capability for NLGEOM - check to see which licence you're picking up by looking at the top of Workbench or manually configure Workbench first.

I just checked out my support. On their charts for the professional version it's written that the nonlinear geometrical capabilities are large deflection only for beams and shells and stress stiffening for beams, shells and solids. This seems to confirm your suspicion.
