Hello everyone !

I'm trying to run a simulation corresponding to my case starting from the tutorial multiRegionHeateRadiation.
For now, I only worked on the regions and the mesh, I didn't change any properties of the used regions (heater, bottomAir, leftSolid which I renamed Solid).

At my previous step the simulation was structured as 3 layers with as dimensions 0.02x0.02x0.01m :
- heater = bottom
- Solid = middle
- bottomAir = top
and this simulation was running without any problems.

Now I wanted to change the positions of the regions heater and Solid. I would like to have "heater" as a 0.02m square in the middle and "Solid" surrounds "heater" as a 0.04m square and "bottomAir" as a gas flow on the top of these 2 solid regions.

When I launch the simulation I received this error in "log.chtMultiRegionSimpleFoam :

In fact the file mapDist was not created, but it was in the previous simulation I ran. I don't know at which step of the simulation it is created, this is why I'm asking for your help The mesh is correct, I can open it in paraview.

Hi krankwelle31,
I had the same problem and I could solve the error by increasing the maxDynListLength in the file /constant/air/viewFactorsDict.
