my pupil sometimes disappears for a few moments for the last few years should I be worried?
It happens in both eyes, but when it does only occurs in one of them

If your pupil actually disappears, you have cause to be worried. This is something that does not normally happen. In fact, I would say that it cannot happen.

When you say it 'disappears'? Does it go to fully open or closed?

Consider steady two-dimensional heat conduction in
a square cross section (3 cm 3 3 cm, k 5 20 W/m·K, a 5
6.694 3 1026 m2/s) with constant prescribed temperature
of 100°C and 300°C at the top and bottom surfaces, respectively. The left surface is exposed to a constant heat flux of
1000 W/m2 while the right surface is in contact with a convective environment (h = 45 W/m2·K) at 20°C. Using a uniform mesh size of Dx 5 Dy, determine (a) finite difference
equations and (b) the nodal temperatures using Gauss-Seidel
