In the Flow Calculation panel on the top left, select the Flow Solver Type to be used for solving the chosen partial differential equations from the pull-down menu (EJ, SimpleFFT, or LIR). EJ cannot be selected for solving Brinkman equations.

It is also possible to choose Load from file to import the result file (*.gdr) of a fluid flow simulation previously executed with FlowDict or AddiDict. In this case, computational time is saved by re-using this result, and no additional flow simulation must be executed.
