October 15, July 28, Leave anything that does not make sense to you as default.

To create the surface mesh, one has to create a rule for each BC: 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.

I have created the boundary conditions with no big problems, and have moved on to create the surface meshes. Originally Posted by Claudio My understanding, and attempt, was to have the normals all pointing into the flow region.

Grid on curved surface. One suspicion, however, is that the surfaces are not correctly oriented. The only checkbox you need for now is the “use absolute height” option. What are good values to stop the process at?

December 13, April 29, There are then 5 check boxes and 7 parameters to be set. June 13, I have completed a mesh for your geometry see image below.

How are these supposed to be handled?

The STL file got first imported into Blender and then exported to enGrid the Blender files engrkd in the archive as well.

I haven’t had the chance to look at your case yet. That is to match the Blender definition of top, front, etc.

I have downloaded your files and will examine them in details.

If I open them with enGrid, will they show the set of parameters you used to make the steps work? All times are GMT Blender is very useful to split the geometry into different boundary codes patches — easier than the “P” and feature angle approach.

If engtid want, you could use a very simple geometry and play around with the parameters to see what they do. What do these ratios represent? The length is absolute. Any obvious reason why?
