Defining materials for Simcenter 3D Thermal/Flow, Electronic Systems Cooling, and Space Systems Thermal

When you are working in the Simcenter 3D Thermal/Flow, Simcenter 3D Electronic Systems Cooling, or Simcenter 3D Space Systems Thermal environments, materials are classified as either thermal (solid) or fluid.

Thermal materials

Thermal materials can be isotropic, orthotropic, or anisotropic. You can define the following:

• A number of general thermal material properties, such as thermal conductivity or specific heat, that you define in the Material dialog boxes.

• Thermo-optical properties for radiation models with the Thermo-Optical Properties or Thermo-Optical Properties – Advanced modeling objects.

• Properties for ablation or charring with the Ablation-Charring modeling object.

For more information, see Thermal material properties.

Fluid materials

Fluid materials can be defined as a pure substance, an homogeneous mixture of perfect gases, or an immiscible fluid mixture. You can define the following:

• A number of general fluid material properties, such as viscosity, molar mass, gas constant, specific heat, or density, that you define in the Material dialog box.

• A mixture of substances of using a Homogenous Gas Mixture modeling object.

• Non-Newtonian fluid materials using a Non-Newtonian Fluid modeling object.

• An immiscible fluid mixture using a Immiscible Fluid Mixture modeling object.

Fluid materials can only be assigned to 3D meshes, which represent separately enclosed fluid domains, or 1D meshes used in duct networks. You can model multiple fluids in a single enclosed fluid domain using the Homogeneous Gas Mixture, Immiscible Fluid Mixture, and Tracer Fluid modeling objects.

When you use 1D duct elements, the fluid material must be a pure substance.

For more information, see Fluid materialsfor heat transfer and flow analyses.
