lsengine

MatrixOperations.lsengine(type_='', enginename='', matrix='', option='', **kwargs)

Creates a linear solver engine.

Mechanical APDL Command: *LSENGINE

Parameters:

type_str

Specifies the algorithm to be used:

• DSS - MKL sparse linear solver.

• LAPACK - LAPACK dense matrix linear solver (default if applied to dense matrices).

• DSP - Distributed sparse solver (default for sparse matrices).

enginenamestr

Name used to identify this engine. Must be specified.

matrixstr

Name of the matrix to solve.

optionstr

Option to control the memory mode of the DSS solver (used only if Type = DSS):

• INCORE - In-core memory mode.

• OUTOFCORE - Out-of-core memory mode.

Notes

Warning

This function contains specificities regarding the argument definitions. Please refer to the command documentation for further explanations.

Argument Descriptions

• type_ : str - Specifies the algorithm to be used:

  • DSS - MKL sparse linear solver.

  • LAPACK - LAPACK dense matrix linear solver (default if applied to dense matrices).

  • DSP - Distributed sparse solver (default for sparse matrices).

• enginename : str - Name used to identify this engine. Must be specified.

• matrix : str - Name of the matrix to solve.

• option : str - Option to control the memory mode of the DSS solver (used only if Type =

DSS):

• INCORE - In-core memory mode.

• OUTOFCORE - Out-of-core memory mode.

This command creates a linear solver engine.

The DSS and DSP solvers can only be used with sparse matrices. For dense matrices, use the LAPACK solver.
