Thanks for your suggestion. That's a good idea. It's for sure that the direction of normal() at boundaries points outwards.

Many cheers, Bruno. It's sorted out. Eventually, GroovyBC works. BTW, normal() follows right-hand rule as most of other codes, doesn't it?

I made up a parabolic profile for velocity inlet using groovyBC as
inletL
{
type groovyBC;
variables "yp=pts().y;minY=min(yp);maxY=max(yp);rad=0.5*(max Y-minY);vavg=0.23;";
valueExpression...

Thanks, L. Well, I suppose the polynomial example for scalar variables. Is it also applicable for vector variables like velocity?

Thanks, Kilroy. Unfortunately, I couldn't find it in the OF version used.

Actually, the question is similar to setting up the inlet velocity profile for fully-dveloped laminar flow.

how to set up inlet velocity profile

Hey,

I am setting up a polynomial velocity profile (say, Ux = C1+C2*y+C3*y^2) for a velocity inlet. Any idea for it?

Cheers,
Raymond
