Performs the solve (forward/backward substitution) of a factorized
APDL Command: *LSBAC
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
solvector – Name of vector that will contain the solution vectors upon
completion. Must be predefined as a *VEC vector or *DMAT matrix.
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
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
