Description: The quasi-static analysis procedure that is used for problems with time-dependent material response (creep, swelling, viscoelasticity, and two-layer viscoplasticity) can now use the iterative linear equation solver. For large, well-conditioned problems the iterative solver is likely to be faster than the direct equation solver for quasi-static analysis.
