I add enetgy equation to icoFoam and build icoHeatFoam. after I make blockMesh and boundrycondition I face with this error:

what does this error mean and how can I debug it?
tnx for any help(I attached my case)

Hello,

As given in error message this is due to dimension mismatch
"
incompatible dimensions for operation
[U[0 1 -2 0 0 0 0] ] == [-grad(p)[1 -2 -2 0 0 0 0] ]". Dimensions on both side of == operator should match.

Regards,

I corrected it.
but after that I faced with this error:

How can I consider continuity in my case?What should my boundrycondition to consider continuity?

With out your case and your BC we can do little.

Are you sure or scalar equation is right implemented?
