Ansys PCG Solver

[fm756]

Hi,

I currently using Ansys 13 APDL with the PCG Solver for a contact analysis. I am running multiple analysis that are writting over each other one after an other. Each time i'm extracting the important information and save them within a .txt file.

My problem is that PCG solver are itterative and i would like to save the maximum number of itterations by the solver for the analysis.(Those informations are usually plotted in the .PCS file) I am currently trying with the following APDL code:

*get,PCG,active,,solu,CGITER

but i always obtain 0. Is there any other way to save the maximum number of itteration that the PCG solver does for solving an analysis.

Thanks
Felix

Hi Felix,

Have you tried adding
set,last
before your *get code in /post1?

When using Workbench environment, program automatically creates a variable (_PCGITER) where is stored the number of iterations done by the PCG solver.

Hi Carles

I've tried in both /post1 and /solu and they are both giving me 0.

Thanks for the help
