Modify Solution Controls in Ansys

When you export the .cdb, .dat, or .inp file from Advanced Material Exchange, solution controls will be added to the file to help improve convergence during the structural analysis. The solution controls will take on the following form:

NROPT,FULL,,OFF
PRED,OFF,,OFF
NSUBST,100,100,100
NEQIT,1000
TIME,1
CNVTOL,F,,,0

Refer to the Ansys documentation for further details on what each term above represents.

If you would like to modify these solution controls, simply open the file in a text editor and modify the appropriate values.
