Local Mesh Deformation for accelerated parametric studies based on the Finite Element Method

This paper presents an approach for enhancing the efficiency of two-dimensional Finite Element Method analysis in parametric studies or optimisation process of microwave components. The new approach involves local mesh deformation applied near the elements that are modified during computations. Since in the proposed approach the topology of the mesh remains unchanged, a new mesh does not have to be generated from scratch when the geometry changes. In effect, substantial reduction of time taken by parametric studies or optimization of microwave components can be achieved, especially if the technique is combined with local Model-Order Reduction, called macromodeling.
