Mass source and momentum
 
Hi!

I have mixture of two species A and B. According to sign convention given in the guide, for source its positive and negative for sink. What should be the sign for the momentum term for the same source and sink?

I'm asking because I'm getting nasty reults.

Thanks.

Re: Mass source and momentum
 
negative sign for momentum means you're removing momentum, so the same logic as for the species... post some more problem details and people might be able to help you out
