They allow solving examples that are by classical approaches either unsolvable or solvable at a cost of high memory and time of computation. The adaptive processes described in the paper are still limited to 2D computations. Their computer implementation is highly nontrivial every physical field in a multiphysics task is generally solved on a different mesh satisfying its specific features and in 3D the number of possible adaptive steps is many times higher.

The described adaptive techniques may represent a powerful tool for the monolithic solution of complex multiphysics problems. Obtaining the results, moreover, requires less time and computer memory. Karban, P. However, there is a value at which the results converge and further mesh refinement does not increase accuracy. This powerful design tool has significantly improved both the standard of engineering designs and the methodology of the design process in many industrial applications.

In the s FEA was proposed for use in stochastic modelling for numerically solving probability models [24] and later for reliability assessment. From Wikipedia, the free encyclopedia. Numerical method for solving physical or engineering problems.

Solution methods. Colours indicate that the analyst has set material properties for each zone, in this case a conducting wire coil in orange; a ferromagnetic component perhaps iron in light blue; and air in grey. Although the geometry may seem simple, it would be very challenging to calculate the magnetic field for this setup without FEM software, using equations alone.

FEM solution to the problem at left, involving a cylindrically shaped magnetic shield. The ferromagnetic cylindrical part is shielding the area inside the cylinder by diverting the magnetic field created by the coil rectangular area on the right. The color represents the amplitude of the magnetic flux density , as indicated by the scale in the inset legend, red being high amplitude. The area inside the cylinder is low amplitude dark blue, with widely spaced lines of magnetic flux , which suggests that the shield is performing as it was designed to.
