Hi, foamers,

Would be really grateful if someone could help me with this.

Basically, I'm creating a model for wind-driven-rain studies. I'm using latest openFoam.org v12 with solver multiphaseEuler and PIMPLE.

The model I created based on tutorial named aachenBomb and hotBoxs, since I suppose they are both using cloud and particle stuffs.

However, I encountered error "request for viscosityModel physicalProperties from objectRegistry region0 failed available objects of type viscosityModel are 0()"

I have ensured both air and water have their defined in their respective files physicalProperties.air and physicalProperties.water. I check 0 files and schemes and solvers. Just the error persist.

anyone has any suggestion or tips for this one. Please hit me a little bit.

I attached log.foamRun file here. Struggled for weeks, really need a hand here.

I found when OF reading fvModel file, it is request for viscosityModel physicalProperties from objectRegistry region0 failed.

So how can I define the proper physicalProperties? Any function or entry can be used in fvModel file?
