Hello,

what can cause a "unknown matrix type combination"?

This is the debug information I get when running a case:

--> FOAM Warning : From function void Foam::lduMatrix::operator-=(const Foam::lduMatrix&) in file matrices/lduMatrix/lduMatrix/lduMatrixOperations.C at line 286 Unknown matrix type combination

this : diagonal:0 symmetric:0 asymmetric:1
A : diagonal:0 symmetric:0 asymmetric:0


As the one for p should be symmetric, I assume it's missing. Line 286 is part of the code checking whether a matrix combination is valid, it doesn't tell me anything about the root cause.
