Grid Card Syntax (EOR)

STOMP-EOR grids are structured and orthogonal to nearly orthogonal, with hexahedral grid cells. A number of different ways of specifying grids are available in STOMP-EOR:  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.

Input Data Types

Character string (e.g., van Genuchten, porosity, m^3/s, Roe Superbee)

Integer (no alpha characters, special characters, or punctuation) (e.g., 1, 32, 195634)

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

Keyword (exact formatting required) (e.g., file, ~Solution Control Card, binary file)

For non-uniform grids, the location of the cell edges is specified, therefore, the number of cell surfaces specified will be one more than the number of grid cells in that direction.
