Abstract
A method is described for generating a hexahedral mesh from a geological model, including: generating a three-dimensional tetrahedral mesh from the geological model; getting a 3D hexahedral mesh based on a tetrahedral mesh, including: verticalizing the tetrahedral mesh to make the faults and boundaries of the domain vertical; calculating a global 2D parameterization for a reference horizon of the verticalized mesh; determining a 2D grid formed from quadrilaterals representing the reference horizon based on the global parameterization; getting a 3D hexahedral mesh by propagation of the grid to the other horizons of the model; and restoring the initial geometry of the faults; and implementing an additional processing of the mesh in order to structure the mesh near each singular point.
