Hello,
It is said that solving a 2-d transient-state diffusion problem by finite
element method is very expensive comparing with the finite-difference ADI
method specialy when the coefficients (material properties) are functions
of time. Can anyone there direct me some references about this topic ?
My question may be clarified as follows:
(1) what is most expensive part in the finite element processing for
the problem ?, and
(2) how more expensive the FE method is than FD-ADI method for
a same problem (in a simple geometrical domain and for a simple
boundary problem)?
Thank you very much!
