Hello friends,

I'm studying a slurry flow inside a 2d rectangular tank......now the problem is when i start iterating the conmtinuity line in the residual graph falls above the divergence criterai i.e 10e-3....in the initial stage of iteration it is below 10e-3 but after sometime it goes to 10e-2.....i want it to be well below 10e-3.....plz help.......

Hi, Try reducing the under-relaxation factor for pressure and see the difference. Hope it works.
