dual porosity model in petrel/eclipse

[vibhore]

The problem I'm facing is that in Eclipse 2009, for a dual porosity model there is a grid duplication for matrix/fracture. I've run a box-model by using DX,DYY,DZ and TOPS.
While I have maps for thickness and tops for various seams of a sector and I'm creating a grid in Petrel 2014 and I plan to import the grid and use it in ECLIPSE 2009. Petrel gives only output in ZCORN and COORD. How can I make double grids for matrix/fracture.
Is there a work around for this problem.

I got the solution to the problem, so I thought to put here also for others benefit.
There is a keyword DPGRID used in Runspec section. This allows us to input only matrix ZCORN and COORD and it will automatically create the fracture grids.
