ABL profile and temperature field, humidity field

Afr1yne · October 16, 2024, 22:36

Hi,foamer
I'm working on a project to simulate a transient 2D mountain wind field, applying atmBoundaryLayer condition, taking into account both the temperature and humidity fields. It is not possible to calculate humidity and temperature at present, do you have any ideas?
Thanks in advance

I've tried multicomponentFluid modules and fluid modules but neither can be calculated,Displays floating-point overflow, maybe it can't be adapted to ABL conditions in openfoam11

Hi,all
who have any ideas?

Check your setup - it does work fine with temperature. Ofc, there's no facility for modelling humidity in the distributed OpenFOAM versions ... but google and you will find some examples where others have developed new thermo models to account for it.

Hi Tobermory,thank you for replied.i trying coding humidity model,and reset my case.
