Under option #2 WERAMI outputs the value of the requested property on a two-dimensional grid, the structure of this data file is illustrated by the following example: LINE 1: plstauI LINE 2: 100 100 673.0008 30000.05 8.080791 LINE 3: 505.0495 LINE 4: T(K) P(bars) LINE N: 0.470475E-06 LINE N+1: 0.471061E-06 ... The variables are: LINE 1 title LINE 2 in some versions LINE 2 may be broken into two lines. number of grid points in x (XPTS) & y (YPTS) direction; minimum value of x variable; minimum value of y variable; increment of x variable. LINE 3 increment of y variable. LINE 4 x variable name, y variable name LINE N the remaining lines are the value of the property of interest at the grid points as defined by the grid from line 2, beginning at the minimum x-y coordinate. these are written ((property_value(i,j),i=1,xpts),j=1,ypts).
