NAME
Grid_getNumVars
SYNOPSIS
Grid_getNumVars(integer, intent(in) :: gridStruct, integer, intent(out) :: nVar)
DESCRIPTION
Returns the number of variables in each mesh data structure. Allows us to write more flexible code that is not dependent on NUNK_VARS and NFACE_VARS e.t.c.
ARGUMENTS
gridStruct -- Integer value representing mesh data structure nVar -- Number of mesh variables in gridStruct
