Hi,
I'm using icoTopoFoam to study the use of topological changes in the mesh; with the sliders i'm ok, but I have problems wit layer addition/removal. The following case stops when it tries to remove a cell layer: ![]() I've tried to set up another case, but this one doesn't even start, the solver gives this error: --> FOAM FATAL ERROR : gradientInternalCoeffs cannot be called for a calculatedFvPatchField. You are probably trying to solve for a field with a calculated or default boundary conditions. From function calculatedFvPatchField<type>::gradientInternalCoef fs() const in file fields/fvPatchFields/basicFvPatchFields/calculated/calculatedFvPatchField.H at line 174. FOAM exiting ![]() I've double-checked my boundary conditions and all other things but I can't find anything wrong, can you give me some help? Thanks Andrea |

This is the message you get when a calculated boundary condition is created in one of your fields as default. The code cannot work with the calculated patch field type because calculated means "I don't know what to do here".
Find out which field has got the calculated b.c. and how it got there, once you fix that, all will be well. Hrv

Well, i've rewritten another case from scratch, I don't know what's changed exactely but now it works. If you find it useful, you can include this case as an example case in openfoam.
btw, i haven't clear yet if there is some real difference between insideSlider and outsideSlider, can someone explain me this? I mean, can insideSlider and outsideSlider be safely swapped? Bye Andrea ![]() |

Hi,
I still have problems with the 3d case, when it's time to remove a layer the courant number rises quickly until it aborts. I've tried several things like changing the grid, the piston speed and other things but with no results, so... what should I care about when setting up a layer addition/removal case? Thanks Andrea |
