Hi friend, I have a trouble
 
Hi friend,

I have a trouble which I want to modify the U. I mean I want to keep the initial U to a new variable and after solver, I like to add this quatity to U again. But there are some errors. Could you please help me.

volScalarField Uin = UEqn.A();
...
U += Uin;

Errors:

icoFoam.C:120: error: no match for ˜operator+=U in ˜U += Uin"
