Error when trying to generate sculpt mesh by providing (base) input mesh

Coreform Cubit Meshing
#1

Hi Coreform community and team,

I am trying to use sculpt via CLI to generate a hexahedral mesh of the human brain. I provide the command with the triangulated surface of the brain (STL) and a base grid (exodus) that I generated using the voxels of the original MRI image. My goal here is to match the (interior uniform grid) generated hexahedral brain mesh with the MRI image voxels.

I have provided the error (
error-terminal.txt (6.0 KB)
) I get after running the following command:
sculpt -j 8 -i input-file.i

Please let me know if I should provide any more information.

Thank you in advance for your assistance!

Andy

Hi Andy,

Welcome to the forum. Can you upload your diatom and .i files? It looks like there is something wrong in the input because by the time you get to the smoothing stage you get the message

Smoothing 0 hexes on 8 processors

That seems to indicate that there was not any mesh generated.

Thanks,
Karl

Thank you.

The forum does not let me upload the .i and .diatom files so I will upload as text:

brain.diatom.txt (129 Bytes)
input-file.i.txt (147 Bytes)

Hi Andy,

Your input file and diatom file are about as simple as they get. Can you upload your brain.stl file as well so I can run the problem?

Thanks,
Karl
