Hello Dheeraj,

Based on the applied frequency the area through which the current flows in a coil will change due to the skin effect. Now if the mesh is not refined enough to capture the skin depth the resistance computed will not be correct. Maxwell does the volume meshing, so the skin depth has to be represented by th mesh element. 

HFSS does a surface meshing and the surface behaviour can be captured very well. 

When you are carrying out an analysis in eddy current simulation, mesh is created for the adaptive frequency mentioned in the Analysis setup. This mesh is used for the analysis of other frequency points. So make sure the adaptive frequency mentioned is closer to the maximum frequency. Â
