Unit syntax error with meshvol

In the variables section, I want to add meshvol into an equation of a variable. But (even if I only define a variable with the expression "meshvol") the error appears, and in the unit column it doesnt show me any unit.
When I solve my model, I can plot the meshvol as usual with the correct unit m^2.
How can I get the volume of each element as a variable to use it in an equation?
Thanks in advance, Peter.

You need to define the varible explicitly on domain (or boundary) level. 'meshvol' has different definition (and unit) on different geometrical levels. This is why you cannot define the variable on 'Entire model'.
