*SUBSTRUCTURE GENERATE

Keyword type: step

This procedure is used to generate a substructure and store the stiffness matrix using the *SUBSTRUCTURE MATRIX OUTPUT keyword card. No loading should be applied.

There is one optional parameter: SOLVER. It determines the package used to solve the ensuing system of equations. The following solvers can be selected:

- PARDISO
- SPOOLES [3,4].

Default is the first solver which has been installed of the following list: PARDISO, SPOOLES. If none is installed, a substructure generation is not possible.

First line:

- *SUBSTRUCTURE GENERATE
- Enter SOLVER, if needed, and its value.

    Example:

    *SUBSTRUCTURE GENERATE,SOLVER=PARDISO

defines a substructure generation step and selects the PARDISO solver as linear equation solver in the step. For this to work, the PARDISO solver must have been linked with CalculiX.
