Dear members
i have some problem with defining constant value at inlet boundaries for advection-diffusion equation.assigning the constant value of (c=c0) at each time step at inlet boundary leads to some oscillation near boundary.please
kindly help me to know what numerical treatment is needed to avoid such oscillations.
Regards.
