This　study　investigates　the　impact　of　an　inclined　magnetic　field　(MHD)　on　entropy　generation　in　double　diffusive　natural　convective　flow　in　a　wavy　enclosure　filled　with　a　non-Newtonian　Casson　fluid.　The　Galerkin　Finite　Element　Method　(GFEM)　is　employed　to　numerically　solve　the　standard　formulation,　utilizing　quadratic　polynomials　for　momentum　interpolation　and　a　linear　interpolating　function　for　model　approximation.　The　discretized　system　is　resolved　using　Newton＇s　approach　and　PARDISO＇s　matrix　factorization.　Through　simulations　of　varying　ranges　of　Rayleigh　numbers　(1e(3)　＜=　Ra　＜=　1e(5)),　Casson　parameter　(0.1　＜=　beta　＜=　10),　Hartmann　numbers　(0　＜=　Ha　＜=　40),　Lewis　numbers　(0.1　＜=　Le　＜=　5),　and　inclined　angle　gamma　(0　＜=　gamma　＜=　60o),　the　study　provides　valuable　insights　into　the　behavior　of　double　diffusive　natural　convection　in　the　wavy　enclosure.　Isotherms,　iso-concentration　contours,　and　streamlines　are　analyzed　to　assess　different　input　distributions,　and　the　study　presents　graphical　representations　and　tabular　data　on　heat　transfer,　mass　transfer　rate,　and　entropy　production.
