A Finite Volume Method using a Quadtree Non-Uniform Structured Mesh for Modeling in Electrical Capacitance Tomography

Abstract An electric field solver based on a finite volume method using refined structural mesh is proposed to implement quadtree structure and estimate the flux in cell. Numerical experiments were carried out uniform non-uniform meshes assess quality of numerical modeling. The verification calculations circular symmetry electrical capacitance tomography (ECT) probe allows effectiveness refinement reduce number elements. Experiments showed that even moderate level sufficient significantly simulation error occurs modeling cylindrical probes. reduced elements applied implementation ensures high speed forward problem calculations.
