Material for Fluid¶
In one sentence: Assign density, viscosity, and thermal properties to a fluid domain for Elmer flow or conjugate heat transfer analysis.
Overview¶
Workbench: FEM
Menu: FEM → Model → Materials → Material for Fluid
Creates a fluid material object for use with the Elmer Flow Equation (Navier-Stokes) or Heat Equation (conjugate heat transfer).
