| Jun 28, 2017 at 16:55 | comment | added | Will.Mo | will do! thanks again for the help | |
| Jun 28, 2017 at 15:48 | comment | added | Will.Mo | Yes, once I figure it out, I'd be happy to share what I came up with -- is stackexchange the right forum for that? | |
| Jun 28, 2017 at 14:50 | comment | added | user21 | @Will.Mo, sounds interesting. Maybe at some point you can share your insights? | |
| Jun 28, 2017 at 14:42 | comment | added | Will.Mo | my project involves solving an elliptic PDE with an "oblique boundary condition". I've managed to get something that works for the "regular" case (where the direction of the derivative is nowhere tangential to the boundary) and now I'm working on the irregular case, and I believe I will need a bit more control with the boundary mesh. | |
| Jun 28, 2017 at 14:29 | comment | added | user21 | @Will.Mo, I must admit that when I searched for it on the web page I did not find it either only when I wanted to add it to the tutorial I did see that I had already done it.... haha. Out of curiosity and if you can say, what are you working on? | |
| Jun 28, 2017 at 14:27 | comment | added | Will.Mo | Sorry, I missed that. Thanks for the tips, and thanks for teaching me how to search the Mathematica tutorials correctly :). | |

@Will.Mo, SetNumericalRegionElementMesh is actually in the mentioned tutorial. Look for the section called 'Numerical Regions'. Since SetNumericalRegionElementMesh is there only as program code, it might not be searchable in a browser. It is, however, searchable in the tutorial notebook under FEMDocumentation/tutorial/ElementMeshCreation. If you have other suggestions for improvement, let me know.

| Jun 28, 2017 at 11:47 | comment | added | Will.Mo | Thanks for your thoughtful reply. The very last comment is exactly what I need. I understand that this function SetNumericalRegionElementMesh can pass the information that allows ToElementMesh to construct a good representation of something like a disk. The information contained in a boundary mesh is insufficient. The tutorial you mention does not seem to cover SetNumericalRegionElementMesh. This seems to provide the functionality needed to create an element mesh with a custom boundary mesh -- which was the problem that motivated my question. So that was indeed helpful! | |
