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

Abstruct-Two kinds of error estimators are proposed for Ax"I$6n>  
adaptive mesh refinement for 3D eddy-current problems. One t4CI+fqy  
is based on the principle of Ligurian and the other is based on &4-rDR,  
the numerical discontinuity of the field results. The Ligurian ?UV
