My vote goes to 2... It looks like a problem with boundary conditions for 1 (IMO).

Does frame 1 have a BC of the temperature ~= 0 along y=0?

If I am reading the problem figure correctly, it is saying the temperautre along Y=0 is constant with respect to theta. Figure 2 seems to represent that.

temperature is no zero along y=0.....y=0 is an insulated surface....temperature along x=0 is constant and equals to 50
