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 MCONTR 20 in a .p3rc file If running in POLYMAN, select the simulation and click on Tools > Options > Polyflow. In the box that appears, under “Modify .p3rc configuration file”, add the keyword MCONTR 20 If running in Workbench environment, right click on Solution cell and click on Preferences > Polyflow. In the box that appears, under “Modify .p3rc configuration file”, add the keyword MCONTR 20 If running simulations in standalone mode, then create a .p3rc file containing the keyword MCONTR 20 and launch the POLYFLOW calculation with the command polyflow –s .p3rc output.lst If the trouble persists, the argument of MCONTR should be increased (up to 30, 40…or beyond)
