Key improvements in 18.1

Simulator. Hydraulic fracture model based on LGR and changing rock properties in SRV (Stimulated Rock Volume) zone and fracture zone (FRACTURE_PLANE, FRACTURE_TEMPLATE, FRACTURE_WELL, FRACTURE_STAGE etc.)

Simulator. In CPU+GPU calculation NVidia® Volta® cards are supported.

Model Designer. Graphical Interface. According to the active development of Model Designer functionality all pre-processing options will be moved from simulator graphical interface to Model Designer. Simulator graphical interface will be used for post-processing results. In 18.1 the following functionality has been moved from graphical interface to Model Designer:

– RP editing with mouse holding Shift button; – Conversion of table RP to Corey and LET correlation; – Introducing of proppant properties table; – Introducing of flow function.
