hi HallsofIvy, Thanks for your reply. Yep you are right. But I am facing here another problem. The problem is that I have no condition at r=0; Instead of r=0 I have another condition that is ri(internal radius)=0. So I can not eliminate one. Bye

actually it is a wave diffusion equation in hollow cylindrical problem.. I think I can solve this problem.

here I attached the equation with the boundary value. Please see the attachment.

Hi all, I am facing difficulties about boundary condition in Hollow Cylinder. its like wave diffusion equation in hollow cylinder. can anyone help me out to solve this problem. I need some good reverences. Thank you
