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

Abstruct-Two kinds of error estimators are proposed for u\MxQIo'u  
adaptive mesh refinement for 3D eddy-current problems. One }I MV@z B  
is based on the principle of Ligurian and the other is based on V2xvuDHI  
the numerical discontinuity of the field results. The Ligurian BPl% SL  
estimators have been established from the complex vector field k ]T  
quantities and can be electric or magnetic. The duality between Kv:Rvo  
Hand E formulations is reflected in the estimators based on the vC^{,
