Hi,

I defined an function with funkySetFields that raise die kinematic viscosity to a higher level.

Is it possible to set the funkySetFields for the entire calculation (every timestep) ?

thanks - max

In swak4Foam there is a functionObject manipulateField that could do that (as long as the viscosity-Field is available under that name in memory). But I'm not totally sure whether this is the best way to implement a viscosity model

Okay, that means that there is no way to create a numerical beach with funkySetFields?!
I have problems with the installation of swak4foam. That is why I tried it with funkySetFields.

It is. Depending on two things:

- the viscosity field is registered (so that swak can find it)
- it is not updated between the time you modify it and the time it is used

Both of this depends on the solver

Ah okay.
I am creating waves with groovyBC and the solver is interFoam.

If I take a turbulence model and then modify the turbulent viscosity. Would that work?

Thank you

Depends on the turbulence model (whether it makes nut available "in memory"). With kEpsilon for instance you might get lucky

okay, thank you. I will give it a try...
