General Grid Interface (GGI) connections refer to the class of grid connections where the grid on either side of the two connected surfaces does not match. In general, GGI connections permit non-matching of node location, element type, surface extent, surface shape and even non-matching of the flow physics across the connection.

2008年8月1日 · no sure about all those errors, but the GGI is a "general grid interface" where you can have multiple grids with faces that touch eachother.

2016年10月31日 · 我想开发一个类似于ami或者ggi的这样的一个连接面，但是不会像ami或者ggi这么复杂和通用。 我在看源代码的时候，发现AMI和GGI都有不用层次的依赖关系，像overlapGgi依赖于overlapGgiPolyPatch等等，很多层的依赖关系。

The GGI is a common interface in the domain of CFD simulation of turbomachines like the water turbinerunnersusedbytheelectricalpowerplantstoproduceelectricity.Separate3Dmeshesaregenerally

2010年1月13日 · In the help-document of GGI (General Grid Interface) Connections, GGI connections permit non-matching of node location, element type, surface extent, surface shape and even non-matching of the flow physics across the connection.

2008年1月1日 · Face interpolation is executed using the Generalised Grid Interface (GGI) interpolation method, as proposed by Beaudoin and Jasak (2008) [41]. This method involves summing the weighted...

2009年2月6日 · In OpenFOAM-1.5-dev, there is a tutorial in icoDyMFoam called mixerGgi that will show you the mechanics. Other cases, including partial overlap GGI, cyclic GGI etc will doubtless follow. I am particularly looking forward to getting the …

Domain interfaces that use GGI connections are a very powerful and flexible mesh connection method, but they do require some additional computational effort and memory, and may introduce numerical inaccuracy compared to an equivalent computation that does not use GGI connections.

To connect dissimilar meshes, an intersection algorithm is used to find the overlapping parts of each mesh face at the interface; for details, see GGI and MFR Theory in the CFX-Solver Theory Guide. The CFX-Solver must decide the most appropriate way to perform this intersection.
