Multicomponent mixing

Sam

I am trying to model a multispecies mixing problem, where an agitator is rotated inside a vessel with the fluid inside. I have chosen two non reactive materials, water and glycerine.

Once I start the simulation, the solution diverges. Can anyone help me and explain possibly what is wrong. I have tried setting the multi component parameters according to the Star user guide, but there is obviously still something missing.

I am very desperate to get this working so all help and suggestions would be appreciated.

Cheers
