Why does ANSYS Fluent report a floating point exception at the first iteration when working with the non-equilibrium thermal model for porous cell zones (NETM)?
January 25, 2023 at 7:16 amFAQParticipant
The non-equilibrium thermal model (NETM) for porous zones in ANSYS Fluent requires the porosity to be smaller than 1 which is the default value. If you forget to adjust this value the solution diverges in the first iteration. Fluent also prints a warning after activating the model to remind you that this value must be adjusted.
