Hi, Could you help me? I have this equation (a heat equation with a source term dependent to time): k*div(grad(temp)) = Ro*cp*dt(temp)+0.009*t^(-1.6)*F0*Alpha*(l-x)*y*temp*cos(omega*t)/(j) It is time dependent. when I run it, Flexpde says"divided by zero". I changed that halt but I still has devided by zero. I think this is becuase time term (t^-1.6)in the source term will be very low. What should I do? Sincerely, Mehdi |
