Design environment and anisotropic adaptive meshing in computational magnets
Design environment and anisotropic adaptive meshing in computational magnets
This thesis describes the implementation of a novel parametric system for the design of electromagnetic devices. This system has two separate environments for the two different classes of users. An expert designer has a full range of facilities available for creating a parametric model of the device, while a non-expert user has options, configured by the expert, for easily generating variations of this model. This implementation reduces the need for all users of the finite element analysis software to be experts in electromagnetic modelling of the device. The implementation of a variational geometry engine for constraining the geometry is also described.
The use of adaptive meshing techniques is very important to the use of parametric modelling, as control of the finite element mesh over a wide range of dimensional variations is extremely difficult. The current techniques used for adaptive refinement are discussed.
A novel form of ansiotropic adaptive meshing based upon a dynamic bubble system is implemented and discussed. The adaption is for any electromagnetic model solved as a static or time harmonic problem. This system uses the physical positioning of ellipses within space as the basis for the generation of a new mesh. The size of these ellipses is based upon field values calculated from a previous coarser mesh. Results from use of this adaptive meshing technique for a range of magnetic models are discussed.

Abstract
This thesis describes the implementation of a novel parametric system for the design of electromagnetic devices. This system has two separate environments for the two different classes of users. An expert designer has a full range of facilities available for creating a parametric model of the device, while a non-expert user has options, configured by the expert, for easily generating variations of this model. This implementation reduces the need for all users of the finite element analysis software to be experts in electromagnetic modelling of the device. The implementation of a variational geometry engine for constraining the geometry is also described.
The use of adaptive meshing techniques is very important to the use of parametric modelling, as control of the finite element mesh over a wide range of dimensional variations is extremely difficult. The current techniques used for adaptive refinement are discussed.
A novel form of ansiotropic adaptive meshing based upon a dynamic bubble system is implemented and discussed. The adaption is for any electromagnetic model solved as a static or time harmonic problem. This system uses the physical positioning of ellipses within space as the basis for the generation of a new mesh. The size of these ellipses is based upon field values calculated from a previous coarser mesh. Results from use of this adaptive meshing technique for a range of magnetic models are discussed.
