Hi. I changed boundary condition as you suggested. My simulation still
blows up. The Courant numbers always start with small like shown below,

Mean and max Courant Numbers = 1.06693e-14 5.67538e-14

These numbers diverges to infinity later in time. I tried using
several different time steps but still have same behavior. Does
wrong boundary condition cause this symptom? or is it caused by
something else.. like maybe using wrong scheme?

Thanks again.
