groovyBC error: velocity profile (2D) >> what's wrong?
groovyBC error
Hi everybody!
I'm trying to implement a parabolic velocity profile to my inlet (2D), cordinates: (x,z) . Inlet is located between the coordinates z= 0 and z=0.001. the parabolic equation for this profile is
Velocity_x_direction = 99*z - 98072*z².
This equation in this range of points (between z= 0 and z=0.001) give the exact velocity profile that I need.
I already add "libs" lines in the end of ControlDict file (I'm using swak4Foam to use GroovyBC):
