[其它]An Approach to Adaptive Mesh Refinement for Three-Dimensional Eddy-Current Computations

Abstruct-Two kinds of error estimators are proposed for bd2QQ1[1vh  
adaptive mesh refinement for 3D eddy-current problems. One >uFFTik  
is based on the principle of Ligurian and the other is based on  p+-IvU  
the numerical discontinuity of the field results. The Ligurian 27MwZz  
estimators have been established from the complex vector field Xm<|m#  
quantities and can be electric or magnetic. The duality between '_ys4hz}  
Hand E formulations is reflected in the estimators based on the 4jzjrG  
discontinuity of the field results. Edge-division technique and a t(}g;O-  
‘local Laplace’ algorithm have been used in the mesh refinement ^OK;swDW  
implementation. A comparison between the .. wJu9.
