Isotropic turbulence by DNS using FVM -- CFD Online Discussion Forums

September 20, 2016, 13:34	Isotropic turbulence by DNS using FVM	#1
prak_1989 New Member Prakash Join Date: Jan 2015 Posts: 14 Rep Power: 11	I am trying to validate some of the statistics in isotropic turbulence by DNS. I am using Finite volume method, where the inviscid and viscous fluxes at the faces are interpolated by symmetric average. I am getting a negative pressure which leads to NaN after certain iterations. What could be the problem ? I am stuck for more than a week, someone please suggest me something. Thanks
