## Description

This command is used to control the FEM solver (write the input file, edit it, and trigger the solver).

## Usage

- Select the solver object in the tree view, e.g., for CalcuilX solver
**SolverCcxTools**. - There are several ways to invoke the command:
- Press the Solver job control button.
- Select the
**Solve → Solver job control**option from the menu. - Use the keyboard shortcut: S then T.

- Optionally, edit working directory.
- Optionally, select analysis type.
- Click Write .inp file to write the input file.
- Optionally, click Edit .inp file.
- Input file will open so you can edit it and save by Ctrl+S.

- Click Run CalculiX to trigger the solver.
- The solution may take considerable time for large models.

## Notes

- Default working directory can be changed in
**Edit → Preferences → FEM** - Controls for other solvers may differ.
- The simplified version of the command is Run solver calculation.
