The flow solver process can be stopped when clicking Cancel or Stop in the progress dialog. Depending on the solver’s internal processes and actual memory usage, canceling the computation may not be instantaneous.

If the Cancel button is clicked, the calculation stops without reporting a meaningful result: no permeability, mean velocity, or pressure drop is reported, and no flow field is written on the hard drive.

If the Stop button is pressed then the solver treats the current simulation as being converged. The solver reports a permeability, mean velocity or pressure drop and a flow field is written on the hard drive.

If the memory requirements are close to maximal computer capacities, you may need to use the Task Manager to stop the FlowDict process. Access the Windows Task Manager dialog by clicking with the right mouse button on the Windows task bar. Then, select the corresponding solver executable (e.g., find LIR.exe by searching) and click End task.
