May 3, How are these supposed to be handled? I have downloaded your files and will examine them in details.
One suspicion, however, is that the surfaces are not correctly oriented. Originally Posted by Claudio My understanding, and attempt, was to have the normals all pointing into engird flow region.

The STL file got first imported into Blender and then exported to enGrid the Blender files are in the archive as well. June 28, I consider those values converged ;- 5. If I open them with enGrid, will they show the set of parameters you used to make the steps work? So for the box the normals point inward, and for the hull they point outward. I haven’t had the chance to look at your case yet.
Blender is very useful to split the geometry into different boundary codes patches — easier than the “P” and feature angle approach. If you want, you could use a very simple geometry and play around with the parameters to see what they do. The only checkbox you need for now is the “use absolute height” option. June 13, Oliver, thanks for your reply.
December 13, To create the surface mesh, one has to create a rule for each BC: What do these ratios represent? Grid on curved surface. You can find the several steps here: April 29, Same enGrid file as above 5 I assumed the surface grid was good enough and try to move forward to make the prismatic tutoriial layer: We are still looking for volunteers to improve the documentation GitHub wiki pages.
Here are the links to all of them: Algebraic Model for Variance – grid size surface field. The length is absolute.
Leave anything that does not make sense to you as default. You do not need to specify rules for every patch; if you don’t specify a rule, enGrid will relax the mesh size towards enggid maximal allowed edge length. Sorry I didn’t upload the complete set of enGrid files, didn’t realize it made more than the file I saved.

All times are GMT Hi Claudio, I’ll try to answer engridd questions: June 12, July 28, There are then 5 check boxes and 7 parameters to be set. Hope somebody can help.
I have completed a mesh for your geometry see image below. My understanding, and attempt, was to have the normals all pointing into the flow region. BB code is On.
The time now is It is tjtorial required though. What are good values to stop the process at? That is to match the Blender definition of top, front, etc.
Add Thread to del. Cheers, Oliver Last edited by ogloth; June 13, at How to extract surface from plot3d grid NASA chimera tutorila. I might not have achieved what I intended though October 15, Originally Posted by Claudio.
