Extrap

Hello Comsol gurus,

I am doing a CFD simulation in which I need to use the solution of another CFD simulation. I need to take a "slice" of the solution and use it in another geometry. As I understand, there are two ways, one is to import the data and use it in another file and the other way is to couple two models in the same file.

I have tried the second way with satisfactory results but I want to try the other one. I exported the data as a spreadsheet in a .txt file and I used an interpolation function in the new file. I inserted the interpolation function at the inlet of my geometry (in the laminar flow moduel settings: inlet) and tried to solve.

I have an error called "Extrap not supported. Error in multiphysics compilation". So far I have not found any entry or thread about this error. Either the solution is too simple or this error is not so common, I asume is the first one. What can I do? I am sure I missing something but I can't find it

Regards and thank you in advance

Miguel
