METHOD OF CALCULATING PHYSICAL VALUE, NUMERICAL ANALYSIS METHOD, PROGRAMME FOR CALCULATING PHYSICAL VALUE, NUMERICAL ANALYSIS PROGRAMME, DEVICE FOR CALCULATING PHYSICAL VALUE AND NUMERICAL ANALYSIS DEVICE Russian patent published in 2014 - IPC G06F17/50 G06F17/10 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to methods, devices and computer-readable media for calculating a physical value and numerical analysis. A computer-executed method of calculating a physical value comprises a physical value calculation step of calculating, using a central processing unit, physical values in an analysis domain divided into a plurality of divided domains using a discretised governing equation which uses values not requiring coordinates (Vertex) of vertices of the divided domains and connectivity information (Connectivity) of the vertices and which is derived based on a weighted residual method and a calculation data model in which volumes of the divided domains and characteristic values of boundary surface indicating characteristics of boundary surfaces of adjacent ones of the divided domains are provided as the values not requiring coordinates (Vertex) of vertices of the divided domains and connectivity information (Connectivity) of the vertices. The discretised governing equation and the calculation data model are stored in a storage device.

EFFECT: reduced operating load when forming a calculation data model and low computational load in the resolving process without deterioration of analysis accuracy.
