Options

Select Filter Efficiency from the pull-down menu and click the Option’s Edit… button to open a dialog to enter or edit the simulation options. Choose a Result File Name for the result file (*.gdr) fitting to your current project.

The filter efficiency simulation parameters are organized under the tabs: Filter Experiment, Constituent Materials, Particles, Solver, and Output. The Equations & References tab gives a summary of the used equations and symbols which are explained in more detail in this user guide.

Tabs of the Filter Efficiency dialog
Filter Experiment Set the mean flow velocity and the boundary conditions. Constituent Materials Define fluid type and temperature. Set material IDs and parameters for porous layers. Particles Select particle sizes and their start positions. Set all parameters that govern the particle motion and define collision and adhesion models. Solver Select the flow solver, set the stopping criteria and define the computational resources. Output Choose which data will be stored for visualization.
