Smile No changes

Dear Rob
I didn't change your system folder.I just changed boundary condition
I'll send the case for you via email to check it.

Smile Problem Solved

Dear Rob and Alberto
Hi
I finally simulated my case without any problem. I just defined a section on outlet with atmosphere boundary condition( like dam break example in tut.)
Here I wan to give...

Question Strange Results

I've changed some boundary conditions related to outlet and the following results were obtained. At the initail times the flow is inward in the outlet and over time it became outward. I don't know...

I've just changed k, epsilon and velocity or the inflow height. If you see the simulated model by yourself you can see the inward flow at the outlet. (turning glyph on at 1 sec in Interfoam_mohammad...

Question Results

Thanks Rob,
I will do it and inform you from the results.
Thanks to god, I didn't have any simulation abrupt. But In the result I think the outlet acts like wall that is the flow in the outlet is...

Dear Robert I got why you chose those values....

Dear Robert
I got why you chose those values. I have a question about total pressure for outlet. I remembered you told me to set 1e5 for p0. But You didn't do that in your simulation. Could you...

Thanks for your reply dear friend!
I'm simulating a free surface flow in the structure as seen in the first post. The flow passes the pipe it impacts on the front wall.
I use Interfoam as solver...

Reasonable Time Step for Turbulent Flow Simulation

Dear Foamers
Hi
What time step should we use for simulation of highly turbulent flows? I Tried a lot of ways to prevent blowing out the simulation but I didn't succeed. I'm not sure about the time...
