In the Measured Experiment panel, enter fluid properties and the thickness of the media used during the experiments. These values may differ from the corresponding values in the Predicted Experiment panel.

Enter the Thickness of media, Density of fluid and Viscosity of fluid which were used in measurement.

Enter Velocity / Pressure drop pairs from real measurements or simulated experiments. From these values the Forchheimer Approximation extrapolates the values for the desired Predicted Experiment. A quadratic polynomial is fit to the given velocity / pressure drop pairs with quadratic regression by least squares analysis. At least two of these pairs are required.

With Extrapolate from given Velocity/Pressure pairs checked by default, a plain table for velocity and pressure drop is displayed below. Adjust the Number of Parameters according to the number of given pairs and enter the velocity / pressure drop pairs into the table.

If Extrapolate from .gdr result files is chosen, a table for result files in .gdr format appears. Adjust the Number of Parameters according to the number of given .gdr files.

Browse to the given .gdr files until the table is filled. These .gdr files must be result files from previous FlowDict flow simulations, e.g., Navier-Stokes(-Brinkman). The velocity / pressure drop pairs are then extracted from the given files.
