[blockMesh] Error - Block Mesh

MaralMohajer · April 13, 2016, 09:26

Hi everyone ,

I'm facing some problems creating mesh via blockMesh.
my vertices , blocks and arcs are mentioned below. Could you please help me with ?

without running blockMesh, how can I see my vertex and arcs? parafoam -block just is available after crerating blockMesh , do we have sth if there are even errors in blockMesh ?

I'm attaching necessary files from error as well as verex and blocks and edges .

Regards
Maral

Hi,

Without running blockMesh there is no mesh for OF to show you any details.

You can try writing out your geometry to a VTK format (the legacy type) and then load that in Paraview: http://www.vtk.org/wp-content/upload...le-formats.pdf

The error you encounter is the most common type of error in blockMesh. Basically the "face x has no ... " means that the vertices you have used to define the face DO NOT define a face. Most of the time this error is caused by an incorrect vertex numbering of a face.

I have provided a solution in a few of the posts here, so perhaps you can take a look at that.

Hope this helps.

Cheers,
Antimony
