Flow based upscaling of Permeability

[Jasper]

Hi All,

I am a new MRST user. I need to do the flow based upscaling of permeability. I am using this https://www.sintef.no/projectweb/mrst/modules/upscaling/single-phase-upscaling/ example code to execute this task. For that, I have already exported the grdecl file from petrel and loaded in MRST. When I tried to run the following code: 

%%

try

require upscaling coarsegrid

catch %#ok<CTCH>

mrstModule add upscaling coarsegrid

end

verbose = true;

%%

G = readGRDECL("C:\Users\44772\Desktop\GmgV1\GmgV1.GRDECL");

display(G)

%% The coarse grid

upscaled = [50 50 50];

G_ups = cartGrid(upscaled, cellDims);

G_ups = computeGeometry(G_ups);

I'm getting the this error:

>> G_ups     = cartGrid(upscaled, cellDims);
Not enough input arguments.

Error in cellDims (line 34)
n = numel(ix);
 

Could you please have a look and suggest what should I do?

Best wishes,

Shakhawat

Thank you for your interest in MRST.

Your script does not show if you have a variable named 'cellDims' in your environment.  If you do not, then the statement

    G_ups = cartGrid(upscaled, cellDims)

will, undesirably, include a call to MRST's built-in function 'cellDims' (fullfile(ROOTDIR, 'utils', 'cellDims.m')) and that function expects to be called with two parameters—an existing MRST grid and list of cell indices for which to compute the (X,Y,Z) cell extents/physical dimensions.

If that is not what you intended to do, then I suggest creating an actual variable named 'cellDims' with the real physical dimensions of your upscaled grid.  Otherwise, you should pass the real parameters to into the 'cellDims' function instead.
