## Static Linear Solver

The static linear solver allows for solving static (stationary) linear or linearised problems. It is invoked by the MDL command analysis linear; this command must be specified in the case block.

## 1. MDL Commands

In addition to the MDL command analysis linear, the following commands may be specified in the case block.

gradients istep

Controls the computation of the gradients (strains, stresses, heat transfer, etc.) for the current case. Specifying a positive integer value (e.g. 1) for istep means yes. A value of 0 means no. Default is 0.

gradients_only yes|no

Specifies whether only gradients (and reaction forces) should be computed, while the solution vector is defined solely by the the initial conditions and the boundary conditions. Default is no.
