enGrid Surface grid parameters — CFD Online Discussion Forums
If you want, you could use a very simple geometry and play around with the parameters to see what they do. Sorry I didn’t upload the complete set of enGrid files, didn’t realize it made more than the file I saved. That is to match the Blender definition of top, front, etc. If I open them with enGrid, will they show the set of parameters you used to make the steps work?
I haven’t had the chance to look at your case yet. June 13, Here are the links to all of them: To create the surface mesh, one has to create a rule for each BC: Blender is very useful to split the geometry into different boundary codes patches — easier than the “P” and feature angle approach. One tutorixl, 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 the flow region.
Grid on curved surface. Hi Claudio, I’ll try to answer your questions: What are good values to stop the process at? I have completed a mesh for your geometry see image below.
April 29, The time now is Add Thread to del. 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.
Algebraic Model for Variance – grid size surface field. My understanding, and attempt, was to have the normals all pointing into the flow region. Originally Posted by Claudio.

The STL file got first imported into Blender and then exported to enGrid the Blender files are in the archive as well. December 13, June 12, Cheers, Oliver Last edited by ogloth; June 13, at All times are GMT What does the 0. Same enGrid file as above 5 I assumed the surface grid was good enough and try to move forward to make the prismatic boundary layer: October 15, I have created the boundary conditions with no big problems, and have moved engrd to create the surface meshes.
I consider those values converged ;- 5.

May 3, The only checkbox you need for now is the “use absolute height” option. How to extract surface from plot3d grid NASA chimera mesh. There are then 5 check boxes and 7 parameters to be set.
