FOAM exiting

Hi Ehsan,

Works fine for me and I tested with OpenFOAM 2.2.0. Perhaps you accidentally modified a file or perhaps you didn't run Allrun?

Best regards,

I run it by ./Allrun now
whats the callaoseDict?I can't understand this case.

Do you mean "collapseEdgesDict"? It's for collapseEdges:


$ collapseEdges -help

Usage: collapseEdges [OPTIONS]
  -case <dir>      specify alternate case directory, default is the cwd
  -collapseFaces    Collapse small and sliver faces as well as small edges
                    Collapse faces that are in the face zone indirectPatchFaces
  -constant        include the 'constant/' dir in the times list
  -latestTime      select the latest time
                    do not execute functionObjects
  -noZero          exclude the '0/' dir from the times list, has precedence
                    over the -zeroTime option
  -overwrite        overwrite existing mesh/results files
  -parallel        run in parallel
  -roots <(dir1 .. dirN)>
                    slave root directories for distributed running
  -time <ranges>    comma-separated time ranges - eg, ':10,20,40:70,1000:'
  -srcDoc          display source code in browser
  -doc              display application documentation in browser
  -help            print the usage

Collapses small edges to a point.
Optionally collapse small faces to a point and thin faces to an edge.

Using: OpenFOAM-2.2.0 (see
Build: 2.2.0-5be49240882f

There isn't much to understand on this case. The biggest complication is only related to how the mesh had to be converted from "dat" format to OpenFOAM format.
The other detail that's different from other tutorials is that the internal fields are already initialized with an almost resolved case. Check the file "README" to see what I mean.

thanks.then collapseEdges is for something like modyfing mesh.
another question occurs that what is the role of blockMesh here when the points are specified in dat file.

Here you go:
