UMFPACK sparse linear system solver.

UmfpackSystem is an unsymmetric multi-frontal sparse direct solver used to efficiently solve sparse linear systems.

Tcl form

system Umfpack [-lvalueFact <lvalueFact>]

Example

from femora.core.model import Model

model = Model()
system = model.analysis.system.umfpack(lvalue_fact=4.0)

Create a Umfpack sparse solver system.

Parameters:

Name	Type	Description	Default
lvalue_fact	Optional[float]	Factor controlling matrix storage reallocation sizing. Defaults to None.	None
