Adaptive Mesh Refinement for 2-D Numerical Analysis of Semiconductor Devices
A new mesh refinement criterion is proposed based on the inter-mesh approximation residual (IMAR). IMAR provides an accurate and reliable mesh refinement criterion for the numerical analysis of PDE regardless of its decretization and solution methods. The numerical examples are presented along with the computational algorithm of IMAR and practical scheme of adaptive mesh refinement (AMR) which is implemented on 2D device simulator TSAR.
