Hi,

I am trying to run a simpleFoam model but I am getting a no MRF models present, what could be causing this? The finite volume options present error can be solved by adding a fvoptions file.

Also how do you set the convergence criteria?

Any help would be great

I managed to solve the finite volume issue, but now the solver just stops?

Creating finite volume options from "system/fvOptions"

Selecting finite volume options type limitVelocity
Source: Fluid_Domain
- selecting cells using cellZone fluid_domain
- selected 1570686 cell(s) with volume 5.18396e-06

Then the prompt line appears

Can i know how you managed to solve the "No fvoption error"
