[Opm] Request of information

[Alf Birger Rustad]

Hi Lisi,

I am afraid the question is surprisingly complicated to answer. The hexahedrons we calculate volumes for are cells from corner-point grids. In this case we have chosen to calculate the volume similar to what industry standard reservoir simulators do. The actual calculation is not done in opm though. You will find the call in the EclipseGrid files within opm-parser, with the functions ecl_grid_get_cell_volume1 and ecl_grid_get_cell_volume3. To see how the calculation is actually done, you will need to check out these functions in the Ert code found here:

Cheers,
Alf

Dear Sirs,

I find your web page searching on internet using some keywords.



I am interesting to understand if the available OPM library contains the functions to compute the volume of each cell of a 3D unstructured grid volume made of hexahedron cells type knowing the X-Y-Z of the 8 vertex of each cell.



I hope to have explained well my need. In the case please ask me more.



Best regards
