Compressible Fluid in COMET -- CFD Online Discussion Forums

February 15, 2005, 18:58	Compressible Fluid in COMET	#1
saang Guest Posts: n/a	I have tried to implement compressible fluid with free surface flow by defining "density in user subroutine" for specie 1. Actually, it likes there are 2 materials in one domain (Domain Mat is air (constant density)and Specie 1 is water (compressible density)). But the solution is blown up. Does anyone face this problem before and how you guys tackle it? By the way, i am doing fine to solve compressible fluid in the regular domain (one material in one domain)
