36 Chapter 4 For a REGULAR grid: [xpinp] [ypinp] [alpinp] [mxinp] [myinp] [dxinp] [dyinp] geographic location (x−coordinate) of the origin of the input grid in problem coordinates (in m) if Cartesian coordinates are used or in degrees if spherical coordinates are use (see command COORD). Default: [xpinp] = 0. In case of spherical coordinates there is no default, the user must give a value. geographic location (y−coordinate) of the origin of the input grid in problem coordinates (in m) if Cartesian coordinates are used or in degrees if spherical coordinates are use (see command COORD). Default: [ypinp] = 0. In case of spherical coordinates there is no default, the user must give a value. direction of the positive x−axis of the input grid (in degrees, Cartesian convention). See command COORD. Default: [alpinp] = 0. number of meshes in x−direction of the input grid (this number is one less than the number of grid points in this direction!). number of meshes in y−direction of the input grid (this number is one less than the number of grid points in this direction!). In 1D-mode, [myinp] should be 0. mesh size in x−direction of the input grid, in m in case of Cartesian coordinates or in degrees if spherical coordinates are used, see command COORD. mesh size in y−direction of the input grid, in m in case of Cartesian coordinates or in degrees if spherical coordinates are used, see command COORD. In 1D-mode, [dyinp] may have any value. Default: [dyinp] = [dxinp]. For a CURVILINEAR input (not fully tested for spherical coordinates): [mxinp] [myinp] number of meshes in ξ−direction of the input grid (this number is one less than the number of grid points in this direction!). Default: [mxinp] = [mxc]. number of meshes in η−direction of the input grid (this number is one less than the number of grid points in this direction!). Default: [myinp] = [myc]. [stagrx] staggered x ′ −direction with respect to computational grid; default: 0. Note: e.g. [stagrx]=0.5 means that the grid points are shifted a half step in x ′ −direction; in many flow models x−velocities are defined in points shifted a half step in x ′ −direction. [stagry] staggered y ′ −direction with respect to computational grid; default: 0. Note: e.g. [stagry]=0.5 means that the grid points are shifted a half step in
Description of commands 37 y ′ −direction; in many flow models y−velocities are defined in points shifted a half step in y ′ −direction. EXCEPTION certain points inside the given grid that are to be ignored during the computation can be identified by means of an exception value as given in the corresponding input file as controlled by the command READINP. NOT FOR 1D-MODE. [excval] exception value; required if the option EXCEPTION is used. Note: if [fac] ≠ 1 (see command READINP), [excval] must be given as [fac] times the exception value. NONSTATION the variable is nonstationary (given in a time sequence of fields). NOT FOR 1D-MODE.
