Hi foamers,
I have a solver and I used it for quite a while. It retrieve data from a table and read it and use it (I am 100% sure as I did some validations against experimental data). However, there was always this warning of [-Wunused-variable] occurring at compilation for the variable A in createfields.H : Code:
tableParam tableObject("model",mesh); const volScalarField& A = tableObject.getData("A"); False warning: unused variable It seems that the problem is coming from initialization. I changed the second line of the code in different ways but it did not help. So, I would be grateful if you can help me with this issue. |

If the code looks OK, just ignore the warning and get on with other things.

If you really want to get rid of it, just cast it to void.
Code:
tableParam tableObject("model",mesh); const volScalarField& A = tableObject.getData("A"); (void) A; |
