groovyBC and the pow(x,y) function
Hej,
I wanted to implement a velocity profile with groovyBC. Unfortunately, for some reason I cannot use the pow(x,y) with a non integer :-) the following is supposed to be implemented for the velocity
Code:
inlet
{
type groovyBC;
variables "a=0.39556664;b=2.671836655;distance=0.015-sqrt(sqr(pos().y)+sqr(pos().x));";
valueExpression "vector(0,0,b*pow(distance,0.39556664))";
value uniform (0 0 0);
}
where I tried having a instead of the number withing the pow function as well, but then it said it was missing a numerical value. Maybe somebody has an idea. I get a floating point exception and everything points to swak4foam. The error message is
