Cheers, Oliver Last edited by ogloth; June 13, at Add Thread to del. 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: There are then 5 check boxes and 7 parameters to be set.

May 3, How to extract surface from plot3d grid NASA chimera mesh. I might not have achieved what I intended though Originally Posted by Claudio My understanding, and attempt, was to have the normals all pointing into the flow region.

Hope somebody can help. We are still looking for volunteers to improve the documentation GitHub wiki pages.

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. Grid on curved surface. To create the tutotial mesh, one has to create a rule for each BC: It is not required though. If I open them with enGrid, will they show the set of parameters you used to make the steps work? What do these ratios represent?

Any obvious reason why? Blender is very useful to split the geometry into different boundary codes patches tutoriaal easier than the “P” and feature angle approach.

July 28, I have created the boundary conditions with no big problems, and have moved on to create the surface meshes. I have downloaded your files and will examine them in details.

One suspicion, however, is that the surfaces are not correctly oriented. Last edited by ogloth; June 13, at I haven’t had the chance to look at your case yet. That is to match the Blender definition of top, front, etc.

What does the 0. June 28, June 12, How are these supposed to be handled?

The length is absolute. December 13, I have completed a mesh for your geometry see image below.

Oliver, thanks for your reply. October 15, Here are the links to all of them: April 29, So for the box the normals point inward, and for the hull they point outward.

Algebraic Model for Variance – grid size surface field.

Sorry I tutorizl upload the complete set of enGrid files, didn’t realize it made more than the file I saved. If you want, you could tktorial a very simple geometry and play around with the parameters to see what they do.

BB code is On. Hi Claudio, I’ll try to answer your questions: You can find the several steps here: The only checkbox you need for now is the “use absolute height” option. June 13, I consider those values converged ;- 5. The STL file got first imported into Blender and then exported to enGrid the Blender files are in the archive as well.
