lsbac#
- Mapdl.lsbac(enginename='', rhsvector='', solvector='', **kwargs)#
Performs the solve (forward/backward substitution) of a factorized linear system.
APDL Command:
*LSBAC
- Parameters:
- enginename
Name used to identify this engine. Must have been previously created using
*LSENGINE
and factorized using*LSFACTOR
.- rhsvector
Name of vector containing the right-hand side (load) vectors as input. Must have been previously defined as a
*VEC
vector or a*DMAT
matrix.- solvector
Name of vector that will contain the solution vectors upon completion. Must be predefined as a
*VEC
vector or*DMAT
matrix.
Notes
This command performs forward and back substitution to obtain the solution to the linear matrix equation Ax = b. The matrix engine must have been previously defined using
*LSENGINE
, and the matrix factored using*LSFACTOR
.You can use the
*DMAT,,,COPY
(or*VEC,,,COPY
) command to copy the load vector to the solution vector in order to predefine it with the appropriate size.
