Hello everyone.
I'm just beginner of OpenFOAM.
I have a few questions.

My situation is :
I was running tutorial case (interDyMFoam/ras/DTC-Hull)
in here, I enlarged domain block and DTC hull
domain block is 100 meter for x-direction, 5meter for y direction, 10meter for z-direction.
And I run it as described in "Allrun"script.
here, i skipped toposet procedure. because I was finding what it was.

so, after I run interDyMFoam, error message was shown.
"Unable to set reference cell for field p. Please supply either pRefCell or pRefPoint"

Q1. Is this error have a relation with toposet?
Q2. Where can I find some information about toposet? I'm so curious what it is and why do this and how it works in OpenFOAM

thanks.

I never done that tutorial but these values are on fvsolution, it means you have an ill-conditioned problem with no specification to the pressure so you have to set a paressure value (pRefValue) to a reference ( a cell pRefCell or a point pRefPoin).

Now I gave a glance at the standard case but the pressure field is properly defined so it shouldn't need the setting of the reference cell for p. Post you /0 folder zipped because if you changed only the mesh it should have been fine.

topoSetDict is useful to manipulate a set of cells/region of the mesh, I advice tou to read the sample file in
/opt/openfoam230/applications/utilities/mesh/manipulation/topoSet
e.g In that tutorial everytime he created a new set of cell(c0) that he refined.

Thank you for your kind reply
For the toposetDict, I'll study the tutorial you said.

and, here, I attatched '0'zipped folder and block Mesh file.
I found that if i skip only toposet and refindmesh procedure, it works.
but after i change blockMesh and enlarge the DTC-scaled.stl 5times larger, error happens.


Many Thanks, Won.

you need to post the errors log too, copy and past the terminal output.

I just noticed that you heavily modified the blockMeshDict and especially the patches, you eliminated some of them. This can be the root of the problem.

Just a note I think you noted that in the BCs some patches are absent, but they are defined implicitly in the included file "setConstraintTypes".

And after reading the /0 files you got me confused, for sure you have some and a lot of errors, keep note that the number of patches declared on blockMeshDict must be the same on the /0 files You deleted some patches on blockMeshDict but you kept them in the zero folder. So modify accordingly you mesh because you didn't only enlarge it but you completely changed it, i can't help you here because paraFoam doesn't work on my machine.

I'll check the B.Cs and 0 Folder.
And here is my error message

I'll modify other scripts, and run it again.

OK, I'll seek a solution.
Thank for your kind advise.
Have a nice day
