solve_pardiso#

planestress.analysis.solver.solve_pardiso(k: lil_array, f: npt.NDArray[np.float64]) → npt.NDArray[np.float64][source]#

Solves a sparse linear system using the pardiso solver.

Parameters:

  • k (lil_array) – N x N sparse matrix of the linear system.

  • f (npt.NDArray[np.float64]) – N x 1 right hand side of the linear system.

Raises:

RuntimeError – If pypardiso is not installed.

Returns:

The solution vector to the sparse linear system of equations.

Return type:

npt.NDArray[np.float64]
