June 28, July 28, What do these ratios engriid December 13, 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: I have completed a mesh for your geometry see image below. Here are the links to all of them: So for the box the normals point inward, and for the hull they point outward.

I consider those values converged ;- 5. I might not have achieved what I intended though The time now is June 12, The only checkbox you need for now is the “use absolute height” option. BB code is On. I haven’t had the chance to look at your case yet. October 15, May 3, You can find the several steps here: Algebraic Model for Variance – grid size surface field. I have created the boundary conditions with no big problems, and have moved on to create the surface meshes.

Hi Claudio, I’ll try to answer your questions: Blender is very useful to split the geometry into different boundary codes patches — easier than the “P” and feature angle approach. What does the 0. How are these supposed to be handled?

Leave anything that does not make sense tjtorial you as default. Originally Posted by Claudio. The length is absolute. If you want, you could use a very simple geometry and play around with the parameters to see what they do.

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. There are then 5 check boxes and 7 parameters to be set. The STL file got first imported into Blender and then exported to enGrid the Blender files are in engriid archive as well.

Last edited by ogloth; June 13, at One suspicion, however, is that the surfaces are not correctly oriented. My understanding, and attempt, was to have the normals all pointing into the flow region. That is to match the Blender definition of top, front, etc. Any obvious reason why? How to extract surface from plot3d grid NASA chimera mesh.

Oliver, thanks for your reply. It is not required though. We are still looking for volunteers to improve the documentation GitHub wiki pages.

June 13, Sorry I didn’t upload the complete set of enGrid files, didn’t realize it made more than the file I saved. If I open them with enGrid, will they show the set of parameters you used to make the steps work? To create the surface mesh, one has to create a rule for each BC: Add Thread to del.
