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)
~Grid Card
Choose one coordinate system option
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.
