Mass loss happened during tds simulation

Please login with a confirmed email address before reporting spam

Hi,

For now, I'm simulating tds (transport of diluted species in porous medium) to figure out the distribution of molecules in specific circumstance. In addition, I'm also trying to calculate mass out from the domain by integrating boundary fluxes at the boundaries over time and measure mass for each time point. So, ideally, the mass of molecules given at initial time point should maintain over time, but I could see mass loss over time.

Could you give me any assistance or comments? Thank you in advance!
