Split_Energy

Summary: Enable the split energy formulation, which is necessary when using CFD2 for flow/thermal simulations with fluids and solids.

Flag:

Split_Energy A

A = 0: Default. Disables the split energy formulation.

A = 1: Enables the split energy formulation.

Description

Set this flag to 1 when using CFD2 in CFD 2016 to simulate flow and thermal if your model has fluids and solids. This is necessary to ensure that nodes are not shared across fluid/solid interfaces.

To run CFD2, you must configure the solver as described in the CFD2 topic.

• Additionally, if your model contains fluids and solids and you are simulating heat transfer, assign 1 for this flag.
• Assign a value of 1 to the mesh_BLSimplex flag.
• Assign a non-zero value to dump_cfd2_file.
