I am new in using COMSOL in solving couple heat and mass transfer process. Using transport of dilute species in porous media (tds) and heat transfer in porous media (ht), and finer mesh, i wasn't able to solve the couple multiphysics problem. After running the simulation i got an error message "The following feature has encountered a problem: Invalid variable for lower limit. Feature: Time-Dependent Solver 1 (sol1/t1)", as shown in the attached image. Please, i need someone to help me figure out how to solve the problem.

Hi,
I cannot really say without looking at the model but you can try checking your mass balance.
