Hallo,

im simulating with InterFoam and now after running InterFoam i have this Error. Seems like not gut.

have anybody an idea what ist the Problem now? i have used the folder: multiphase/InterFoam/ras/ weirOverflow.

Thanks a lot!

Hi Berat,

it appears that there is no water in your domain, have you performed setFields?

Best,

Pablo

[Berati26]

my setFieldsDict look like this,

i think alpha.water 1 means like its Watter in the domain or?

[Berati26]

sorry i forget to Attach the pic. Here it is!

I agree with Pablo, it looks like the water phase is not set correctly. What is the size of your domain? Did you remember to run "setFields" before starting the simulation?

[Berati26]

ok i have uplode my blockMeshdict ... The dimensions are 5.3/8.4/0.9 m

and i have only inlet and outlet patches of the Domain.

Then the Geometry is an Pool like in the Picture. I model it with Sketchup, and i separate export the .stl fils, Inlet Outlet and Walls.
So i have 2 times the patch name Inlet and Outlet...

i think i make something wrong

And no, after i finished snappyHexMesh i direktli run InterFoam. the setFieldsDict i dont run.

The coordinates of the box from your setFieldsDict have to be inside your domain.
Anyway, you should check if setFields worked correctly with paraview.

[Berati26]

and now after running my sefFields i get thiss error

Have somebody an Idea what can i do to fix all this problems?

[TobM]

The error tells you exactly what to do, you have to supply pRefCell or pRefPoint in your fvSolution file. Just look into an interfoam tutorial case.

[eric]

I think you are trying to solve too many problems at once, without understanding the basics. I suggest looking at the damBreak tutorial for interFoam. Understand how the mesh is set up, and how the setFields utility works.

Then you can move to your case. Copy the fvSchemes and fvSolution files from the damBreak tutorial to use as a starting point. You also need to fix the setFieldsDict to match where you actually want water in your domain. Before trying to run interFoam, verify that you have the correct water field in Paraview.

Hallo TobM,

i have lookt in the weirOverflow turorial, but in the fvSolutuion file is no pRefCell or pRefPoint, Where should I keep my mind in order to insert correctly?

[Berati26]

HAllo Eric, im using wairoverflow tutorial, but in all thes tutorial they have only a geometrie from blockMesh . I have the file I created from blockmesh and then my geometry, so i cant not realy compare the tutorial with my case.

[TobM]

One very useful command is grep, use it like this:

grep -R pRefCell *

in tutorials/multiphase/interfoam and you will get a list with all files with occurrences of pRefCell within the interfoam tutorials.

When you don't find something in one tutorial look into another and always google your problem.
