Grid on curved surface. 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. I consider those values converged ;- 5.
Blender is very useful to split the geometry into different boundary codes patches — easier than the “P” and feature angle approach. July 28, How to extract surface from plot3d grid NASA chimera mesh. Hi Claudio, I’ll try to answer your questions: The time now is We are still egrid for volunteers to improve the documentation GitHub wiki pages.
Here are the links to all of them: Last edited by ogloth; June 13, at How are these supposed to be handled? Cheers, Oliver Last edited by ogloth; June 13, at tutoiral To create the surface mesh, one has to create a rule for each BC: That is to match the Blender definition of top, front, etc.
tutoorial Same enGrid file as above 5 I assumed the surface grid was good enough and try to move forward to make the prismatic boundary tytorial You do not need to specify rules for every patch; if you don’t specify a rule, enGrid will relax the mesh size towards the maximal allowed edge length.
The length is absolute. June 13, Algebraic Model for Variance – grid size surface field. You can find the several steps here: May 3, What do these ratios represent?
The STL file got first imported into Blender and then exported to enGrid the Blender files are in the archive as well. I have downloaded your files and will examine them in details. One suspicion, however, is that the surfaces are not correctly oriented. The only checkbox you need for now is the “use absolute height” option. What does the 0. My understanding, and attempt, was to have the normals all pointing into the flow region.

Sorry I didn’t upload the complete set of enGrid files, didn’t realize it made more than the file I saved. Leave anything that does not make sense to you as tytorial. Originally Posted by Claudio.

enGrid Surface grid parameters
Oliver, thanks for your reply. It is not required though.
June 12, December 13, If I open them with enGrid, will they show the set of parameters you used to make the steps work? April 29, What are good values to stop the process at? October 15, I might not have achieved what I intended though If you want, you could use a very simple geometry and play around with the parameters to see what they do.
All times are GMT BB code is On. I have created the boundary conditions with no big problems, and have moved on to create the surface meshes. Hope somebody can help. I have completed a mesh for your geometry see image below.
Any obvious reason why? There are then 5 check boxes and 7 parameters to be set. June 28,
