During I add the temperature equation to cavitatingFoam I Got a problem! The new solver is compiled without any errors. Nevertheless, when I use it the terminal displays:
--> FOAM FATAL ERROR:
incompatible dimensions for operation
[T[0 0 -1 1 0 0 0] ] + [T[1 -3 -1 1 0 0 0] ]

Anyone can help me?

The error is telling you that you are attempting to add a term with the units kelvin per second to a term with a term with the units kilogram kelvin per meter cubed per second. Make sure your temperature equation units/dimensions are consistent throughout. For some help on the dimensions, look at Basic input/output file format.

Further to this discussion, it appears that either the first term should be divided by density, or the second one multiplied by it.
