A question about the EOS9nT

Hello everyone,

I have a question or problem about the EOS9nT in my recent research project. In the attachment you can see the guide example that we downloaded together with the source code. We wonder that as we raise the hydraulic pressure of the element in the INCON file for the nuclide concentration source 100 times, the result shows the nuclide concentration at the neighbored elements is higher than in the concentration of the boundary condition,  what is not really logic. 

We have a task model that we need to shut down the diffusion to do the simulation, the similar effect happens when the transport process is strongly dominated of the advection.

Can some one please tell me the reason of this simulation results? Or how can we avoid this effect?

Or how can I contact the Mr. Moridis?

Thank you very much

X. Li
