heaviside?
 

Dear Open Foam Community,

I am a brand new to OpenFoam.

I would like to create a field like
where toto1 and toto2 are two "constants" and phi is a "volScalarField". Is there a way to do this?

Many thanks in advance,
Martin.

Hi Martine

You could use either of the functions Foam::neg or Foam::pos. These functions return 1 if the argument is negative (positive) and 0 if the argument is positive (negative). I do not know how the functions handles 0, however.

Best regards,

Niels

Indeed!

Thanks so much, Niels!

Martin.
