Hi,

I am experiencing the following error while running MPPICFoam. I tried to change the boundary conditions, I also added a U file. But both didn't solve the problem.

Anyone knows how to solve this error.

Thanks.

--> FOAM FATAL ERROR: 

    request for volVectorField U from objectRegistry region0 failed

The error is already telling you what's wrong...

You are probably telling the cloud to use an object called "U" for the velocity, despite of not being available in your simulation. I suggest you to check again https://github.com/OpenFOAM/OpenFOAM...loudProperties
