Internal Boundary

Hi,

I've seen that now there is internal Boundary. We have to give the following information:

"BOUNDARY": {
            "INTERNAL": [
              {
                "hqrelation_file": "",
                "name": "PONT_A_IN",
                "string_name": "PONT_A_IN",
                "type": "hqrelation_internal"
              }
            ],

Compare to the version 2.8, there is no string for the inner outflow of the inner boundary. How does it works? Does it mean that we have to put a hole in the middle of the mesh?

Cheers,

Quentin

Re: Internal Boundary

Hi Quentin

In BASEMENT v3 there are three types of boundary conditions: standard, internal and linked.

Internal boundary conditions require only one nodestring and can be used to set e.g. a wall inside the mesh.

Linked boundary conditions require two nodestrings which can be separated by a hole in the mesh, but do not necessarily require a hole between them. Linked boundary conditions can e.g. be used to model a culvert or a passage.

Re: Internal Boundary

Hi Matthias,

Thanks for the hint, I was too quick and missed the Internal point.

Cheers,
