comment Solving a PDE containing DiracDelta
@b.gatessucks I tried this code with MatheMatica7. As your advice, it can be solved by MatheMatica8. Thank you.

comment How to set the initial condition? (to make IC and BC consistent)
Your help taught me the principle to harmonize the initial and boundary condition. Thank you. ^^

Your advice helped me to solve the problem. At this time, I realized initial condition should satisfy all the boundary conditions, not only one. Thank you. ^^

comment How to set the initial condition? (to make IC and BC consistent)
Yes, I'm asking what initial condition to choose so that no inconsistent IC and BC error message comes. As your advice, I will make the question shortened. ^^

comment How to set the initial condition? (to make IC and BC consistent)
Thank you for your advice. As following your recommendation, I changed 'If' statement to 'Piecewise' in Fun1[r]. However, the same message was printed. As following your second advice, I found the original initial condition is arbitrary so that Phi[r, Theta, t=0] can be bigger or smaller than 1. As a result, initial condition doesn't have to be consistent. It was my fault that initial condition should be consistent.
