nashiong New Member Join Date: Jun 2010 Posts: 14 Rep Power: 15	hi all: If I solve 2D mass conservation equation. Ht+(HU)x+(HV)y=0 is that possible for me to split it to 2 1D problem by 2 steps? 1). Ht+(HU)x=0 to get H intermediate value, U is value at n time step 2). Ht+(HV)y=0 to correct this intermediate value, V is value at n time step. thanks a lot. I see a lot of people using splitting method to seperate diffusion term and pressure term. but I never see people do that to mass conservation. Last edited by nashiong; July 3, 2010 at 17:47.
