handling multiple regions

[fab6]

Hi, It would be great, if multi-region cases can be handled in fluidfoam as well. E.g. I would like to read scalar values from the different regions for the multiRegionHeater case, which has 5 regions (with non-moving fixed mesh)? Thank you in advance! Fab

Hi I developed very quickly the support for regions/sets. Can you test with the fluidfoam of my fork : https://github.com/CyrilleBonamy/fluidfoam/ ? If you have difficulties to install fluidfoam from my fork, don't hesitate to contact me :-)

Example to use (to read pressure field and associated mesh) :

p = fluidfoam.readfield(path='.', region="bottomWater", name="p", time_name="50")
x, y, z = fluidfoam.readmesh(path='.', region="bottomWater")

Hi, thanks, it works almost for my case: Temperature is read from the regions, though its looking for a sets field, which is not always available.

I used a slight adjustment

import fluidfoam 
T = fluidfoam.readfield(path='../', region="rightRoom", name="T", time_name="50")
print(T)
print(T.max())
T = fluidfoam.readfield(path='../', region="rightWall", name="T", time_name="50")
print(T)
print(T.max())
x, y, z = fluidfoam.readmesh(path='../', region="rightWall")
x, y, z = fluidfoam.readmesh(path='../', region="rightRoom")

Thank you very much!

I am not sure I understand your point about the "sets" field not always being available. Do you have an exemple of such case ?

[fab6]

From my understanding of this error message, fluidfoam is trying to read the sets folder in polyMesh. In the tutorial this is not deleted, e.g. see here but this actually not needed for the simulation. This is why, it is not available in my case.

Sorry, forgot to mention... I just sent the case via email. Thank you very much!

Done #51 :-) Enjoy
