Hello
Why has snappyHexMesh generated time stamps?
namely 0.5 and 1 each with varying files.
How do I view this in paraview using foamToVTK (parafoam doesn't work for me)?
Thanks

I tried placing the '0.5' folder items in the '0' folder as it contained a lot of files that are usually in the '0' folder.. like alpha.water... and p_rgh and a lot more..
and the '1' folder contents(polymesh) I placed in the constant/polymesh folder.
Question:
1)Am I doing things right?
2)why did snappyhexmesh generate all these files.. I thought it just meshes and setfields dict checks/edits alpha.water
3)I get this error after doing the above:

--> FOAM FATAL IO ERROR:
size 250000 is not equal to the given value of 3087288

file: /home/bryce/openfoam30/tutorials/multiphase/interDyMFoam/ras/sloshingTank3D/0/p_rgh from line 18 to line 250030.

From function Field<Type>::Field(const word& keyword, const dictionary&, const label)
in file /home/openfoam/OpenFOAM/OpenFOAM-3.0.1/src/OpenFOAM/lnInclude/Field.C at line 283.

FOAM exiting

Why is the size of p_rgh and U also perfectly limited to 25000
I don't recall setting any limit :O

Please do help

Hi,

By default, snappy will write each stage of the mesh that it generates into a new time folder. In your case, my guess is that you have deltaT set to 0.5 and so each of the meshes is written into that.

If you want to avoid this, use the -overwrite flag for snappyHexMesh and it will be written into the original constant folder.

You get the error in size because I am guessing that you asked snappy to remesh before removing the previous mesh. Remove the previous mesh, reblockMesh and then run snappy with the -overwrite option and it should be fine I think.

Cheers,

Thank you for replying
Yea I figured it out, I was 2 days old with the software.Going on second week now.. so far it 's been great.
Any idea on wall functions and post processing?.. I have a few doubts if you could be kind enough to clear.
Thanks
