POLYFLOW - error message: "A serious internal error has occurred (in CTRWRI)"
This message usually appears when the number of constraints is large compared to the number of variables of the problem. It also happens when a very large flow simulation is defined.
The solution consists of forcing POLYFLOW to allocate larger tables for the constraints. This can be done by using the keyword
in a .p3rc file, or via the POLYMAN environment.
If the trouble persists, the argument of MCONTR should be increased (up to 30, 40, ...or beyond)
