Dear all,

I used a UDS equation to simulate the solute diffusion in a 2D case.

However, I found the volume averaged uds keep decreasing until the end of the diffusion process.

I wonder why the uds is not conserved and if it is possible to make it conserved.

Many thanks for your time. If you have any idea, please reply at your convenience.

Kind regards
