Meshing for Simcenter 3D Thermal/Flow, Electronic Systems Cooling, Space Systems Thermal

The following table provides a guide to the meshing techniques used in thermal and flow analysis.

Meshing technique	Applications	Applicable solver environments	Element types	Material properties
Thermal meshing	Conduction and radiation modeling	Thermal/FlowElectronic Systems CoolingSpace Systems Thermal	3D, 2D, 1D, or 0D	Thermal material properties
3D body-fitted flow meshing	3D flow (CFD) modeling	Thermal/FlowElectronic Systems Cooling	3D fluid elements	Fluid material properties
3D immersed boundary meshing	3D flow (CFD) modeling	Thermal/FlowElectronic Systems Cooling	3D cells	Fluid material properties
Duct network meshing	Duct network modeling	Thermal/FlowElectronic Systems CoolingSpace Systems Thermal	1D duct type	Fluid material properties
Meshing for convection	Modeling heat transfer between surfaces and adjacent fluidNote: An alternative technique is to use convection constraints and modeling objects, which models the fluid implicitly and only requires a thermal mesh.	Thermal/FlowElectronic Systems Cooling	Combination of thermal meshing element types and one of the following:3D fluid elements for body-fitted meshing3D cells for immersed boundary meshingduct network elements	Thermal and fluid material properties

The flow solvers and, the thermal solver when computing conduction, use parabolic elements as linear elements by ignoring the midnodes.

Note:

All of these meshing techniques, except 3D immersed boundary meshing, are also supported by thermal and flow solvers in Multiphysics.
