Changing Mechanical Iterative Solver Limit

    • Matthew Little

      For RAM reasons, I need to run my model using the iterative solver instead of direct.  The iterative gets through the anlaysis, but very slowly since the Limit is set to 1E-8.  Need to run numerous analyses with 20+ steps in each so running it this way is time-prohibitive.

      How can I change the Limit the iterative solver uses as convergence criteria?  I would like to try to set it to 1E-7 to see how much quicker it takes to run.

      It would not be recommended to change these settings and rather keep them as default. Please check the following thread for more information:
