Concept of conformal and non-conformal interface
Could you tell me what's the concept of conformal and non-conformal interface? I tried to search for it online, but I didn't find any good answer. Thanks!
Both are interfaces and there is averaging of data on both sides before transferring to other side.
Conformal interface : An interface with equal no of nodes on both sides.
Non Conformal interface : An interface which does not have equal no of nodes on both sides
Just a minor correction here:
A conformal interface is not defined by an equal number of nodes on both sides.
Instead, the meshes on both sides of the interface have to be conformal:D, which means that every node on one side of the interface can be matched with a node on the other side of the interface with a very low tolerance.
The advantage is that there is no (additional) interpolation necessary at a conformal interface. This makes the computation faster and more accurate.
Consequently, a non-conformal interface can be set at two faces with the same number of nodes.
non conformal interface
Since data across non conformal interface is averaged and transferred is there significant loss in accuracy due to interpolation error?If error is large then which approach is better
1.domain divided in structured meshes joined with non conformal interface.or,
2.unstructured mesh in whole domain without need of interface
I am using multiblock method for horizontal axis wind turbine mesh which is separated in 3 multiblocks and merged
So, a conformal interface can be obtained only for an interface which connects 2 static zones?
