The present disclosure provides a capital construction graphic calculation method, system, electronic device and storage medium, which belongs to the technical field of capital construction engineering and engineering cost. The method determines the overlapping area between the steel bars and the concrete by obtaining the point cloud data of the steel bars and the concrete and the steel bar spacing parameter, extracts the boundary point set of the overlapping area to generate a first grid unit, generates a second grid unit according to the steel bar spacing parameter, corrects the first grid unit through the node coordinate offset between the first grid unit and the second grid unit to generate a third grid unit, and determines the gap filling ratio of the concrete according to the third grid unit to form a continuous boundary model. In this way, the discontinuous boundary error caused by the curved surface overlapping area between the components in the traditional graphic calculation method is effectively eliminated, so that the real geometric shape of the components can be accurately reflected, the precision of the component volume and material consumption calculation is improved, the component volume calculation precision can be improved to ±0.3%, and the material consumption budget accuracy rate reaches 98%.

The invention discloses a method, a module, a numerical simulation platform and equipment for realizing finite volume calculation, relates to the technical field of nuclear reactor core or CFD numerical program design, and solves the problem that finite element calculation and finite volume calculation of the existing nuclear reactor numerical simulation platform are incompatible. According to the technical scheme, the method is characterized in that a 0-order Monomial unit is introduced on the basis of a polynomial Monomial finite element unit, so that the order of a polynomial of the polynomial Monomial finite element unit is reduced to 0 order; and setting the variable discrete type as a 0-order Monomial unit so as to realize switching from finite element calculation to finite volume calculation on a numerical simulation platform. According to the method, expansion is carried out on the basis of the finite element Monomial polynomial unit, and the 0-order Monomial unit type is increased, so that finite volume calculation is supported, and a partial differential equation solving framework of a nuclear reactor numerical simulation platform can support the same interface module to realize finite element and finite volume calculation at the same time.
