Hi there

kind regards as always

Greetings Gowain,

Which exact tutorial are you referring to? I ask this because there are a few tutorials at the wiki: https://github.com/enGits/engrid/wiki/Tutorials

Best regards,

Hi
it is the damper tutorial. the error occurs at the create prismatic boundary layer stage.

I had the same problem, you need to go back to the mesh creation steps and refine the surface mesh at least once more. You also need to redo the volume creation step.

I am runnig into the same problem but further refinement doesn't help
 

Hello,

I am running into the same problem so I did some additional refinement loops and recreated the volume also but I still get the same error message and a warning on the left:

WARNING: RestrictLocalH called, creating mesh-size tree


And Engrid terminates during the meshing process


What's the problem?

Could you check the surface orientation of your mesh?

Another possible cause might be your boundary code, did you do that according to the tutorial?

Hope this helps,
Regards, Redrick

the surface orientation was wrong
 

Hello,

thank you! The surface orientation of the domain was wrong.

Hey
i have the same problem, but turning the orientation didnt help. But maybe i did it wrong. what exactly did you do?
