Hi all, I've been studying MULES for a while and can understand the main ideas of the integrator, but I have some problems interpreting the idea behind the limiter. Usually one uses limiters to limit the flux before integrating temporally. In MULES a flux is given to the integrator, for example, MULES::explicitSolve, this flux is already limited by the advection schemes used to assemble the flux.
Why another limiter function is applied to the flux before integrating temporally? Is it to complete a work partially done by interfaceCompression scheme? Is there some reference, at least similar, to limiter used in MULES? Is it loosely based on what??? All ideas are useful. Regards.
