enGrid Surface grid parameters

One suspicion, however, is that the surfaces are not correctly oriented. What does the 0. Hi Claudio, I’ll try to answer your questions: If you want, you could use a very simple geometry and play around with the parameters to see what they do. The length is absolute. Sorry I didn’t upload the complete set of enGrid files, didn’t realize it made more than the file I saved.

BB code is On.

So for the box the normals point inward, and for the hull they point outward. Leave anything that does not make sense to you as default.

There are then 5 check boxes and 7 parameters to be set. My understanding, and attempt, was to have the normals all pointing into the flow region. 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? It is not required though. June 12, How are these supposed to be handled? I have downloaded your files and will examine them in details.

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. October 15, Originally Posted by Claudio.

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: Last edited by ogloth; June 13, at What are good values to stop the process at?

April 29, We are still looking for volunteers to improve the documentation GitHub wiki pages. I have completed a mesh for your geometry see image below. The STL file got first imported into Blender and then exported to enGrid the Blender files are in the archive as well.

Add Thread to del. July 28, June 28, December 13, I consider those values converged ;- 5.

You can find the several steps here: Oliver, thanks for your reply. Here are the links to all of them: Hope somebody can help. Any obvious reason why?

I have created the boundary conditions with no big problems, and have moved on to create the surface meshes. May 3, To create the surface mesh, one has to create a rule for each BC: Blender is very useful to split tuforial geometry into different boundary codes patches — easier than the “P” and feature angle approach. June 13, The only checkbox you need for now is the “use absolute height” option. Cheers, Oliver Last edited envrid ogloth; June 13, at Grid on curved surface.
