Engrid mesh generation

eebrah · July 28, 2014, 10:32

Greetings,

I want to generate a mesh on Engrid. My CFD case consists of a stl geometry (gully grating) that i have import into blender and I have built the fluid domain around the gully grating. Setting boundary condition by splitting the fluid domain and exporting all geometry from blender into Engrid.

Unfortunately on Engrid, I can't run any meshing operations, i get this error "this seems to be a bug on Engrid" suface operation error, or this seems to be a bug on Engrid updatedesidmesh error. I have followed step by step many tutorials related to Engrid and Blender.

I really appreciate help.

here is the ling of my case : https://drive.google.com/folderview?...mM&usp=sharing

best regards,
ibrahima

Greetings again,

I have tried to get rid of my meshing problem. I have checked my surface integrity on Engrid, suprisingly the surface was not watertight. I fix the surface with blender and export it again into Engrid. Unfortunatulety I am facing the same problem. These errors were noticed : this seems to be a bug on Engrid file ../../surfaceprojection.cpp line 542. file../../updatedesiredmeshdensity.cpp line 72. My question is Do you know what cause thesse errors ? Please help me for somme tips to find solution of this problems ?

best regards,
ibrahim
