The article describes the development of a new tool for calculating the stress-strain state of fields with a complex geological structure in the software package «RN-SIGMA». The computational core allows to make calculations within the framework of elastic models on standard grids (angular point geometry) used in hydrodynamic and geological modeling. The computational core has been tested on a number of examples, including the construction of a model of a real part of the Severo-Komsomolskoye field. The development of new computing core will provide specialists of the PJSC Rosneft Oil Company with an import-independent tool for building 3D geomechanical models.

Materials and methods
When developing the computational core, finite element modeling methods were used to solve the problem of elastic equilibrium of the reservoir, as well as analytical solutions and third-party software products for performing test calculations.
