On computation of 3-D magnetostatic fields of electrophysical apparatus magnet systems

Computation technology based on KOMPOT and KLONDIKE codes for magnetostatic simulations in tokamaks

“…We have developed the computer code KOMPOT [4,5,[12][13][14] to model three-dimensional magnetostatic fields in a precision magnet system of complex geometry in terms of a modified scalar potential. The code uses an FE representation [6] and is capable of modelling a diverse range of magnet systems with ferromagnetic components and complex configured active coils.…”

“…The KOMPOT code implements the FE method in the differential formulation. A calculation mesh is formed by hexahedron elements [4]. The alternative approach based on the integral formulation was implemented in another computer code, KLONDIKE [9].…”

On the Calculation of Concentrated Loads at Finite-Element Mesh Nodes as Equivalents of a Given Spatial Distribution of Volume Force Density

“…Below is described a newly developed procedure NFORCE for integration of the codes calculating ponderomotive forces such as KLONDIKE [4] (analytical solutions, complicated current systems, uniformly-magnetized modules), the code TYPHOON [5] (eddy currents in conducting shells of complex geometry), the code KOMPOT [6] ( precise magnetic field calculations for sophisticated magnet systems with allowance for saturation effect for different retentive and non-retentive materials), and programs used for stress analysis, such as ANSYS [8], FEA [9], CAN [10].…”
