Abstract
In the last decades, a lot of research has been conducted on the insulation of high voltage in vacuum. Recently, an innovative numerical tool, reffered to as Voltage Holding Predictive Model (VHPM), has been developed to asses the voltage holding capability of multi-electrode multi-voltage systems in vacuum. In this paper, a residual-based error estimator with guaranteed error bounds for mixed-hybrid geometric formulations for electrostatics is presented, and a novel algorithm for automatic mesh refinement is proposed, enabling a feature very important in many electrostatic applications and mandatory in the VHPM tool.File in questo prodotto:
