# cpregularize(1)

Program to regularize cornerpoint grids

## NAME

cpregularize - Program to regularize cornerpoint grids

## SYNOPSIS

cpregularize gridfilename=cornerpointgrid.grdecl \[option=value\]

## DESCRIPTION

Program to regularize cornerpoint grids. Caveats: - Only grids with vertical pillars - CornerPointChopper can only chop along existing pillars. In case your asked-for horizontal resolution does not divide the initial number of pillars in x/y, you will not obtain a fully regular grid, but still easier numerically. - Be careful with non-flat top and bottom boundary.

Example usage:

cpregularize gridfilename=grid.grdecl ires=5 jres=5 zres=5 resultgrid=regularizedgrid.grdecl

## OPTIONS

**resultgrid** File name for regular grid.\
 **ires** Resolution in i-direction. Defaults to 1.\
 **jres** Resolution in j-direction. Defaults to 1.\
 **zres** Resolution in z-direction. Defaults to 1.\
 **imin** Can be used to limit the search area for random subsamples. Defaults to minimum i in inputgrid (full model).\
 **imax** Can be used to limit the search area for random subsamples. Defaults to maximum i in inputgrid (full model).\
 **jmin** Analog to imin, but in j-direction. Defaults to minimum j in inputgrid (full model).\
 **jmax** Analog to imax, but in j-direction. Defaults to maximum j in inputgrid (full model).\
 **zmin** Analog to imin, but in z-direction and specified in the grids length unit. Defaults to minimum in inputgrid.\
 **zmax** Analog to imax, but in z-direction and specified in the grids length unit. Defaults to maximum in inputgrid.\
 **minperm** Cut-off value for permeability.
