FEM MaterialFluid
Description
Creates a material for fluid.
The FEM material task panel
Usage
- To create a new MaterialFluid object do one of the following:
- Press the
Material for fluid button. - Select the Model ā Materials ā Material for fluidāā option from the menu.
- Press the
- To edit an existing MaterialFluid object:
- Double-click it in the Tree view.
- The FEM material task panel opens.
- Select a fluid material from the drop-down list. For Computational Fluid Dynamics (CFD), Air or Water are common options.
- Optionally, press the Use this task panel button to modify material properties such as density, kinematic viscosity, thermal conductivity, etc.
- 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 with no fluid assigned.
- Press the Close button to close the task panel.
