Hello Michael, I would say "yes and no". Yes- it seems that this BC works like Robin boundary condition. One region has some non-uniform Robin condition, and the other has the mirror version...

Hello Michael, I suppose that you are working on OF-1.7.1 (please state if otherwise- there were some major changes in this BC). You got quite deep into C++ jungle of boundary condition...

OK, lets do it from the top. First thing to know is how OF stores data. It requires folders: system, constant, <time>. Data are stored in time folders and do not contain any mesh information. Mesh...

Hi Marco, regarding splitting solid region into "heater part" and "fluid wall" part. This is only a good idea if you want to drop the bottom heater part, leaving only the fluid and the wall, and...

Hello Michael, as you pointed out, with the geometry that you have shown, it will be veeery hard (or even impossible) to acquire constant heat flux on the solidBottom-fluid interface. Its just the...
