An explicit Wave Based - Finite element model as alternative to the DtN finite element method KU Leuven
The solution of unbounded Helmholtz problems is the subject of substantial research. If these problems are to be solved using a domain-based discretisation technique like the finite element method (FEM), the computational domain has to be truncated to a bounded region. The unbounded nature of the problem exterior to this truncation is simulated by an appropriate condition on the truncation. A common method to derive this condition is the ...
