We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

What are the differences between MFX/CFX and System Coupling/Fluent?

    • FAQFAQ

      The following is a list comparing MFX to System Coupling (SC): •MFX allows forces to be transferred from a pair of wall boundaries to a set of shell elements (2-to-1 mapping) while SC is limited to 1-to-1 mapping for co-simulation •Mesh smoothing options with CFX are more robust and have more control than Fluent •MFX allows mixed steady/transient couplings and allows restarts from steady-state to transient, neither of which are supported with SC •Cases requiring transient rotor-stator can be solved with MFX/CFX, but cases requiring FSI regions in sliding mesh zones cannot be solved with SC/Fluent •SC/Fluent allows re-meshing whereas MFX is limited to mesh smoothing •MFX does not support many features based on CONTA17* elements, however these are fully supported with SC •SC supports local/shared memory and distributed parallel for MAPDL, whereas MFX only supports local parallel for MAPDL •SC has an easier WB workflow for restarts •Creation of backup points is simpler with SC •SC requires an “ANSYS Structural” or higher license plus any Fluent license, while MFX requires an “ANSYS Mechanical” or higher license plus any CFX/CFD-Flo license, or a single “ANSYS Multiphysics” license, or a single “ANSYS Mechanical CFD-Flo” license •Neither MFX or SC CFX allow for the run to be dynamically changed using “Edit Run in Progress”
