Grid Card Syntax (HYDT-KE)

STOMP-HYDT-KE grids are structured and orthogonal to nearly orthogonal, with hexahedral grid cells. A number of different ways of specifying grids are available in STOMP-HYDT-KE:  Cartesian, Cylindrical, Boundary Fitted (or Curvilinear), Generic Eclipse Grid, EarthVision Sampled Input, and Element and Vertices. STOMP also accommodates grids with displaced adjacent grid cells.

Real (decimal points and exponential notation allowed) (e.g., 0, 0.0, 1.e-12, 1.E+3, 2.345)

Tip

 The grid dimensions that are specified on the Grid Card refer to node surfaces; therefore, for grids with non-uniform spacing, for each grid direction the number of entries required is one plus the number of nodes.  Node volumes are defined by their bounding surfaces. Cylindrical coordinate systems are restricted to azimuthal axes which are less than or equal to 360 degrees.
