Description

Creates a material for fluid.

The FEM material task panel

Usage

1. To create a new MaterialFluid object do one of the following:
   • Press the Material for fluid button.
   • Select the Model → Materials → Material for fluid‏‎ option from the menu.
2. To edit an existing MaterialFluid object:
   • Double-click it in the Tree view.
3. The FEM material task panel opens.
4. Select a fluid type. For Computational Fluid Dynamics (CFD), Air or Water are common options.
5. Provided you are applying fluid to the whole object, don't select any geometrical entities (leave the reference list empty). Fluid will be applied to the whole model. Otherwise assign fluid to particular model domains manually by selecting some of them for each inserted material, if you do that, do not leave any domain of your model without fluid assigned.
6. You can adjust fluid properties such as density, kinematic viscosity, thermal conductivity, etc., a few key fluids are already assigned in the list and they don't need any tweaking.
7. If you make modifications, you can save your customized material.
8. Press the Close button to close the task panel.
