About the artificial viscous of Roe Scheme
 
Hi all!!

I use Roe scheme to solve the 3D channel flow(Les ,low Mach number with preconditioning).

I find if i use small epson number in artificial viscous term,the flow field will decay.

I think the smaller epson the lower dissipation i have .

Am i right??

But the situation is not what i think.

Could someone give me some suggestions ?

Thank you!!
