FTAPI -- FrontTracking Application Programming Interface

The idea behind front tracking is to couple a lower-dimensional surface, which is dynamically tracked with a standard Eulerian solver. Front tracking discretizes and advects a surface representing this material interface which can then be used to adjust solution steps, so that the unwanted mixing between neighboring cells of different materials is prevented. Front tracking API has been coupled to the FLASH code and was used to study whether the current modeling of the RT and RM instabilities in the context of ICF simulations could be improved with the use of a front tracking algorithm.
