Very difficult question about Floworks 2005!!

[schumiGO]

Sorry mate for offtopic(( but i asked near 20 people and nobody could give me amy answers((((((


Question!! HOW can i set boundary condition in plane(Z=0) V=0 (ground effect conditions)...

It means that in Z=0 Velocity is zero and no inflow\outflow.

Help me plz...... thamks a llot... best regards, SchumiGO

I'm not sure if it is the correct method, but I have done it by making making the edge of my computational domain at the ground level, and then setting that wall to symmetry. I have seen some other CFD programs do that when you tell it to use ground effects.

Is it a surface?

If so, just impose no slip conditions??



I think I must be mis-understanding you though - thats too straightforward

Hi mate)
Coll idea))
but......
if flow onli comp domain you couldn't see boundary part.... if you put 40m/s flow of air then you see that y=0 velosity =0 but y = 0.000000001 V= 40 m/s (((((( so it's not correct(((
