[Opm] EQUALS problem with DX

[Stephen, Karl D]

Hi,
I have tried to set up a simple 5 x 5 x 3 cell model with the following grid information:

GRID
-- Size of each cell in X, Y and Z directions

OLDTRAN

EQUALS
-- Keyword   value            X1 X2     Y1 Y2     Z1 Z2
     DX       500  /
                DY       500  /
                DZ        50  /
                TOPS     8000             1 5       1  5      1  1     /


     PERMX    200              1  5      1  5      1  1     /    geological layer 1
     PERMY    150                                           /
     PERMZ     20                                           /
    PORO       0.19                                        /
     NTG        0.95                                        /

     PERMX   1000              1  5      1  5      2  2     /    geological 2
     PERMY    800                                           /
     PERMZ    100                                           /
     PORO       0.20                                        /
     NTG        0.99                                        /

     PERMX    200              1  5      1  5      3  3     /    geological 3
     PERMY    150                                           /
     PERMZ     20                                           /
     PORO       0.19                                        /
     NTG        0.95                                        /

I get the error: "Exception caught: EclipseGrid needs cornerpoint or Cartesian keywords".

Based on the latest version of the manual, I should be able to use EQUALS to set geometry variables. I even tried this with OLDTRAN.

If I use the normal DX, DY, DZ, TOPS keywords and then use EQUALS (not that I want to do this but I tried it to see) I get:

"Exception caught: Fatal error processing EQUALS keyword. Tried to assign not defined keyword DX."

Is there a bug in the code or could/should the manual be updated to highlight this as a feature? It's possible I need to set something for Flow that Eclipse treats as a default?

This is what I have to do:
GRID
-- Size of each cell in X, Y and Z directions

OLDTRAN
DX
     75*500
/
DY
      75*500
/
DZ
      75*50
