Stop KEYOPT from being reset within SOLVE

      I am running an elasto-plastic simulation and verifying it against a Matlab code. The Matlab code uses the B Bar integration method so I have it specified as a key option in Mechanical. Before the solve command, I know KEYOPT,2 is 0 for B Bar integration and see it is correct with ETLIST (see the first image). Once SOLVE is given, Mechanical resets it to 2 for enhanced strain formulation (see the second and third images). How can I prevent this?

      You could use the ETCONTROL command to prevent the reset.
