Hello,

I am looking for a way to perform elementwise operations on a volScalarField. Specifically I want to add/ subtract a constant scalar from every point in the Field. Do I have to define another volScalarField that contains the scalar at every point, or is it possible to directly perform the operation between the volScalarField and the scalar?

Thanks for your help!

I assume that you have seen the https://www.openfoam.com/documentati...api/index.html docs?


Not sure why you cannot simply change the primitive field. Eg (may contain errors)...

volScalarField field( ....);


field.primitiveFieldRef() += 100.0;
field.correctBoundaryConditions();
