Hey Foamers,

i'm working on a 10% bump, and i have some problems where my "inlet" patch meets the "noSlip" wall. The "inlet" has a fixed value velocity of (10 0 0) and obviously the "noSlip" wall has a fixed value velocity of (0 0 0) . There is a discontinuity , which doesn't occur in case of "slip" wall.

Any ideas?

Also, does it matter which BC you place first in the script?
For example ;

inlet
{
type fixedValue;
value uniform (10 0 0);
}
upstream_wall
{
type fixedValue;
value uniform (0 0 0);
}

is different from :

upstream_wall
{
type fixedValue;
value uniform (0 0 0);
}
inlet
{
type fixedValue;
value uniform (10 0 0);
}

Thanks in advance
