Hi everyone, I’d like to ask a very basic question:How to define mesh connectivity information when using nearest-projection?
I’m doing a 3D fluid-solid coupling simulation where the fluid and the solid have an interface for force and displacement data exchange.
I just recently noticed that with nearest-projection need to define the mesh connectivity information.Is it required to provide surface geometry information?Do I need to define surface element or node set in solid? Is there any command in precice-config.xml or solid main file where the surface geometry set definition needs to be written out?I’m still very confused.I’m sorry to ask such a stupid question, but I’m confused.
Here’s the interface coupling as it is now, it doesn’t look like there are any quad or triangle elements defined:
Is the current mapping method actually nearest-neighbor?
This is the precice-config.xml file precice-config.xml (2.6 KB)
This is my solid major file: main.inp (626 Bytes)
Can you please tell me how I can define mesh connectivity information for nearest-projection?
Thank you very much!
Sorry I was confused before, but now I probably understand how to do it.
For the fluid-solid coupling problem I’m doing, I should add surface information to the solid,as described on this page: Configure the CalculiX adapter | preCICE - The Coupling Library
But my element type is C3D8 and I wish to do surface coupling in 3D, can you tell me if this is feasible?
This is my solid mesh:
