Dear FLOW-3D (V11) users and experts,

I have a question about how to use baffles at the in- and outlet of an irregular formed tube.

The problem: water should only flows from top to down inside the tube. Therefore I set baffles at the top (z max) and bottom (z min) of the cartesian mesh block: a third baffle (type hole) was created with a STL file (eq. inside of the tube).

With exact this STL file the fluid region is defined as an initial condition.

The result: FAVOR shows all the time a complete flooded mesh block as fluid surface. I know, there is an other method to get the inside flow by creating a solid block and subtract the STL file with boolean operation, but this I didn't want.

Any help is highly appreciated. Thank you in advance.
