Putting components of darcy velocity in solute transport equation

Please login with a confirmed email address before reporting spam

I wanted to couple solute transport and darcy or brinkman equation to model solute transport in fractured porous media. When I put x-direction velocity of darcy "u" in the solute transport equation and put a constant value for y-direction the model runs but when I put "v" as y-direction velocity in the solute transport eqution an error wiil appear as: undefined value found.
Is there anybody who can help me????
Thank you
