Modelisation of a pipe: Segmentation fault
 

Good morning,

Version: Ansys 5.0.7 (Legal education version)


I'm trying to modelise a simple pipe but when I want to made an "Hybrid Initialization" or run calculation this message appear:

"Received a fatal signal (Segmentation fault)".

After search on the forum I have seen that could come from a variable bad called. But I'm not programming.

The way I have already tested:

-> Directory's name too long.
-> No effect when I put it direct on the C:

-> My model (k-w) bad conditionned
-> No effect when I choose an other model (k-e)

-> Boundary inlet velocity bad conditionned in the "turbulance"
-> Choose "Specification Metod "Intensity and hydraulic Diameter""
-> Turbulence intensity 3.5 % (from the formul given :http://www.cfd-online.com/Wiki/Turbulence_intensity
( with Dh=0.1m and v=2m/s and Re=2e6)
-> No effect

-> I have some warning but I don't know if it could be a problem:
"Warning: Flow boundary zone 9 is adjacent to a solid zone (7). This problem MUST be fixed befor the solution can proceed"


For this other things I hope this not come from:

-> Outlet : Pressure
-> First layer 5e-5 m

-> It's the first time I try a calculation on Fluent

Thanks for your time,

Probably you defined the zone as solid and not as fluid.
So change from solid to fluid and it should work.

Problem resolved
 

It's the solution. Now it's work,

Thanks a lot,:)
