Dear libMesh Users and Developers,
I want to simulate a 3D electrostatic problem in infinite domain. The
electrical potential follows 3D Laplace equation, and it decays to zero (in the
form of 1/r) or reaches a finite value at infinity. I'm looking into infinite
element in libMesh. By searching the mailing list archive, I got to know the
infinite element implemented in libMesh is "mapped wave envelop element" for
acoustic radiation and scattering, my questions are,
1. Could I use the "mapped wave envelop element" for 3D Laplace equation in
infinite domain? i.e. to accurately describe 1/r decay?
2. If yes, what would you suggest in order to use "mapped wave envelop element"
for 3D Laplace?
3. If no, are there any types of infinite element implemented in libMesh for 3D
Laplace?
Thanks for your time.
Regards,
Xikai
