| Topology design optimization control of initial iterative solver tolerance and maximum number tolerance changes. The iterative solver tolerance starts at MAXITERRESTART orders of magnitude larger than SPARSEITERTOL. When EPSILON is larger than 1.E-5, Warning E5131 will be issued and the iterative solver tolerance decreased by one order of magnitude. Adjustments to the tolerance will stop when the tolerance equals SPARSEITERTOL. | 1 ≤ Integer ≤ 10 | 5 |
