An Efficient Modeling and Meshing Method for the Finite Element Calculation of the Ship Magnetic Field

Geometry modeling and meshing are directly related to the effectiveness and accuracy of the finite element calculation. In order to improve above two key technologies, small size ferromagnetic objects on the ship deck are simplified, and the parametric idea is introduced into the ship model meshing. A typical ship model is set up on the platform of software FLUX. The above improved technologies are tested in FLUX in the earth magnetic environment. The experimental results show that the simplified modeling can greatly reduce the amount of calculation, and parametric meshing can effectively improve the computational efficiency, which proves that the above improved method is an efficient method for the finite element calculation of the ship magnetic field.
