Error while running OpenFoam

Dear All,
I would be thankful if you could help me to know how to fix the error I faced in OpenFoam.
the error is as folowing:
FOAM FATAL ERROR:
[3] LHS and RHS of - have different dimensions
dimensions : [0 1 -2 0 0 0 0] - [1 -2 -2 0 0 0 0]
[3]
[3]
[3] From function Foam::dimensionSet Foam:

perator-(const Foam::dimensionSet&, const Foam::dimensionSet&)
From function Foam::dimensionSet Foam:

perator-(const Foam::dimensionSet&, const Foam::dimensionSet&)
[0] in file dimensionSet/dimensionSet.C at line 521.

Hi Philipp
thank you for your replying.
Do you know how can I find which parameter has a wrong dimension.Or which equation has been set wrongly?

Hey,

I am not sure. I would check out all documents in the 0-folder.

Hi!

I think the easiest way for that is finding a tutorial with the same solver, and compare the dimensions of your files in the 0 folder.
You have a wrong dimensions in your 0 folder for any fields. At least usually this is the reason for these errors.

Thank you Simrego,
I exactly used the dimension which are proposed in the solver.
Actually I am using two solvers, So that s why the dimensions are different.
I am interseted in coupling interFoam with immersed boundary.
