I'm getting this error while running my code. could anyone please help me with this?

The error is because you are trying to subtract one field from another, and the units of the two fields are not the same.
See the openFOAM input and output guides for guidance. What equations are you solving? You May have missed a multiplicative factor that has dimensions that will make the fields compatible.
