Hello!

I'm very new to openFoam, so in advance I appreciate any help and information that can be provided!

I'm trying to mesh a thin, flat rectangular plate in a boundary to simulate the flow around this plate. At this point, I'm simply trying to run the blockMesh utility, taking on step at a time, but have been encountering the following message that doesn't mean much to me:

Segmentation fault (core dumped)

I've attached a copy of my blockMeshdict file to help troubleshoot. I've taken a number of looks through the syntax, and have paid careful attention to the ordering of the vertices to ensure the clockwise orientation from the inside perspective. A concern I have is that I have defined my plate as a wall without providing mesh information under blocks (see blockMesh file commentary).

Thanks for any help in advance! I really appreciate any feedback!

Hi,

Your block definition contains fewer than 8 vertices. Even if you are creating wedges or the like, you still need to have 8 vertices in the definition of the hex block.

Cheers,

Thanks Antimony! It seems to have resolved that issue!
