Current　disquisition　is　aimed　to　adumbrate　thermosolutal　convective　diffusion　transport　in　Casson　fluid　filled　in　hexagonal　enclosure　under　effectiveness　of　inclined　magnetic　field.　Partially　iso-concentration　and　iso-temperature　distributions　at　base　wall　of　enclosure　is　provided　along　with　incorporation　of　fillets　at　corners　of　flow　domain.　Governing　formulation　in　2D　are　expressed　in　a　velocity-pressure,　energy　and　concentration　balance　equations.　Numerical　computations　are　executed　by　employing　COMSOL　Multiphysics　software　based　on　finite　element　scheme.　Domain　discretization　in　manifested　by　performing　hybrid　meshing　in　view　of　2D　elements.　Linear　and　quadric　interpolating　polynomials　for　pressure　and　other　associated　distributions　are　capitalized.　Non-linearized　discretization　system　is　handled　by　non-linear　solver　renowned　as　PARADISO.　Results　and　code　validation　is　assured　by　performing　comparison　and　grid　convergence　test　respectively.　The　impact　of　flow　concerning　variables　by　considering　wide　ranges　like　Casson　parameter　(0.1≤β≤10),　Rayleigh　number　(104≤Ra≤107),　Hartmann　number　(20≤Ha≤80)　and　Lewis　number　(0.1≤Le≤10)　on　velocity,　isothermal　and　isoconcentration　fields　are　visualized　through　graphs　and　tables.　Visualization　about　kinetic　energy　along　with　heat　and　mass　transfer　rates　are　disclosed　through　graphs　and　tables.　©　2022　The　Authors
