BEM solutions to exponentially variable coefficient Helmholtz equation of anisotropic media

BEM solutions to exponentially variable coefficient Helmholtz equation of anisotropic media

Boundary value problems (BVPs) governed by a Helmholtz type equation for anisotropic exponentially graded media are solved using Boundary Element Method (BEM). The variable coefficient governing equation is transformed to a constant coefficient equation which is then transformed to a boundary integr...

Zusammenfassung:Boundary value problems (BVPs) governed by a Helmholtz type equation for anisotropic exponentially graded media are solved using Boundary Element Method (BEM). The variable coefficient governing equation is transformed to a constant coefficient equation which is then transformed to a boundary integral equation. The results show the convergence, consistency, and accuracy of the BEM solutions.
