A related project for predicting the acoustics of brass wind instruments

1. OSCILOS_brass

OSCILOS_brass is an acoustic solver for predicting the natural modes of brass wind instruments from their geometry. It was created from the cold flow part of OSCILOS_long. The equations used are the same as those of OSCILOS_long, with OSCILOS_brass supporting more flexible specification of the geometry, several additional boundary conditions, and new output data formats.
