[swak4Foam] slip coded in swak4foam

Hi,

i want to code the slip bc in a groovyBC:

i tried this, switching between a fixed value and slip:

{
type groovyBC;
value uniform (0 0 0);
valueExpression "speed";
gradientExpression "vector(0,-U.y/delta(),0)";
fractionExpression "switch";
evaluateDuringConstruction 0;
}

I think the code is wrong but what?

Thx for helping me out

Christian

For all those interrested

look at groovyBCDirection in the tutorial case of swak
there the fractionExpression is a Tensor not a scalar
