Hi


I solve equations involving physics with vastly different spatial resolution in the 2 regions. Hence the use of different unstructured meshes in these regions. For simplicity let us assume at first that they are not dynamic and that parallel computation is not required.



Define field F1 with an IOobject for mesh 1

Define field F2 with an IOobject for mesh 2


F1 and F2 represent the same physical variable


I could not find a tutorial on how to do the interpolation between F1 and F2.
Would it involve class meshToMesh by any chance ?


Thank you



PS - I dont know if the answer to my question depends on the OpenFOAM variant. I happen to use foam-extend.

Hey celestial,
if i understood you correctly:

(never did this on my own ,) but there is a function constantHeatTransfer that couple two different meshes to allow a heattransfer between them may you can take the sourcecode of it and adapt it for your needs.


greetings

Hello

I dont see the reference to 2 different meshes from the rather short source code of constantHeatTransfer

nor do I see any solver using it

but I will investigate

Thanks for trying to help me

Best
