viscSpongelayer_plane_for_coord Function

private function viscSpongelayer_plane_for_coord(me, coord, n) result(res)

This function calculates the sigma for the planar viscosity spongelayer and multiply with targetState 'viscosity'. This function is currectly used to define viscosity sponge in musubi.

Arguments

Type IntentOptional Attributes Name

barycentric Ids of an elements. 1st index goes over number of elements and 2nd index goes over x,y,z coordinates
integer, intent(in) :: n

Number of arrays to return

Return Value real(kind=rk), (n)

return value
