TIOGA can perform overset grid connectivity in 3-D between multiple unstructured (or structured) meshes that are in a distributed computing environment, i.e. each mesh is partitioned in to multiple parts. It can accept high-order call-back functions to perform p-consistent interpolation and searches for formulations with internal degrees of freedom within a computational element.

TIOGA is free software since it was developed in the personal time of the author. It is expected to serve as an academic/research counterpart for PUNDIT (which is the product of the CREATE A/V program and is export controlled). TIOGA has a subset of the functionality of PUNDIT and is about 3x slower owing to the use of Alternating Digital Tree (ADT) searches as the baseline point-location algorithm.
TIOGA is currently under development with funding from the DoE ExaWind program towards developing overset capability in the DoE NALU code for large scale wind farm simulations
