Hi ,
I've been experimenting with different boundary conditions and am trying to set up velocity profile using groovyBC. At the inlet i require a power law condition given by U=2.5*(z/zr)^0.299...

inlet      
    {
        type            groovyBC;
        variables "Umin=2.5;h=pts().y;a=pow((h/10),0.299);speed=Umin*a;";
         valueExpression    "vector (speed, 0, 0)";
    }

I've attached by simulation domain also, basically a street canyon where my inlet is the left most face with x co-ordinate at -30 and y varying from 40 to 100m. I'm running it in Pisofoam but it keeps giving syntax error at "pow((h/10),0.299);"
" ^^ "
I am also a little confused on how to specify my "y" co-ordinate varying from 40 to 100 in groovy BC, I think i've done it incorrectly.

Any help would be much appreciated.

Thanks in advance,

Regards ,
