I wish to solve Helmholtz equation for an Axi-symmetric geometry.
The problem geometry consists of a excitation source a tube and air box (all rectangles).
Is it possible in equation based modeling?.

Thanks in advance.
Regards,
Arasu

Dear Jesus,

Thanks very much for your reply. In face I used it and found the following problems:

1) Axial symmetry boundary condition does not exist (Does it mean it is implicitly done)
2) The problem has three sub domains and the PDE coefficients (c,f and a) could not be set independently for each of these sub domains.

Look forward to your assistance.

Hello, Thirunavukkarasu

I have tried, and have had no problem in 4.2a. Have you started by "2D axisymmetric" Geometry?
If you have no success, you can attach your model, or better the simplest version of it.

Jesus.
