I am trying to have solute transfer in a flowing fluid only due to convection and not diffusion. If I put diffusivity to be very low, no transfer occurs at all and the concentration of solute is seen to be only at the inlet.
So how to deal with this problem?

Hi,


It is difficult to say why without seeing your file.

But it could be because:

1. Defined convective velocity could be incredibly low so that in the time frame you do not see the change.

2. Defined convective velocity could have a wrong sign convention.

It's not possible to upload the file its saying 'file size error'. I tried clearing all the solution and plots and then uploading but it did'nt happen.
Please help me out...
