That is to match the Blender definition of top, front, etc.

April 29, Grid on curved surface. Here are the links to all of them: How to extract surface from plot3d enyrid NASA chimera mesh. The length is absolute.

How are these supposed to be handled? 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: December 13, There are then 5 check boxes and 7 parameters to be set.

June 13, Add Thread to del. I haven’t had the chance to look at your case yet. If I open them with enGrid, will they show the set of parameters you used to make the steps work? June 28, I might not have achieved what I intended though We are still looking for volunteers to improve the documentation GitHub wiki pages. Hope somebody can help. 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.

Cheers, Oliver Last edited by ogloth; June 13, at My understanding, and attempt, was to have the normals all pointing into the flow region. June 12, The time now is What are good values to stop the process at? To create the surface mesh, one has to create a rule for each BC: The only checkbox you need for now is the “use absolute height” option.

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

I have created the boundary conditions with no big problems, and have moved on to create the surface meshes. I have completed a mesh for your geometry see image below.

October 15, The STL file got first imported into Blender and then exported to enGrid the Blender files are in the archive as well. Originally Posted by Claudio.

I have downloaded your files and will examine them in details. Blender is very useful to split the geometry into different boundary codes patches — easier than the “P” and feature angle approach.

One suspicion, however, is that the surfaces are not correctly oriented. It is not required though. What does the 0. May 3, egnrid Hi Claudio, I’ll try to answer your questions: Any obvious reason why?

BB code is On. If you want, you could use a very simple geometry and play around with the parameters to see what they do.

July 28, What do these ratios represent?
