            After several attempt and re-do of the simulation , finally , I able to display the output with generate magnetic flux and power dissipated in plate, the solution I try recenter the edge current which it's in the middle with boundary condition.The problem may occur because of there is no gap between boundary condition outer layer and plate.Since by default is set by 0.5mm which mean there gap between must not closer than 0.5mm.After changing the placement of plate , I able to generate the output. Power dissipation on different types of crack. Figure 1 :Straight Line Figure 2:Zig-Zag Figure 3:Parallel lines          

       On this week , I try to re-do the simulation by changing materials that may affected result which generate no output.I also try change the size of minimum element size since I assume the minimum value of mesh may be affected of no magnetic flux numb. Figure 1:Plate mesh size changing to 0.1 , default is infinite.                                  Figure 2:Boundary condition mesh size change to 0.2, default is infinite.                                                                     Figure 3:Error found due to limitation geometry sizes.

          So on this week , I do some troubleshoot which I try to reduce quality of mesh.By reducing the number of mesh into maximum element size by 0.8mm for size plate mesh.Since at first , I set 0.5mm which result to error because of too much mesh quality because of the size of mesh is decrease.The size of maximum element size is actually important because it will affected the quality mesh. Figure 1:Mesh size for plate                                                                    Figure 2:Mesh size for boundary condition      Since the size play big role for mesh quality , so I decided to increase the size so it will generate the boundaries more smaller compare to older mesh.This will decrease the time to complete of computation.After the...

          So on this week , I do some troubleshoot with my simulation that can't generate the result which happen because of lack of LU factorization, I do research on website and found that try use another version of COMSOL which may be help , So below the result that I get.                                                                                                                                                                        Figure 1:Mesh quality ...

      On this week , I try with different pattern of crack .. But , unfortunately , it still result the same way with the old plate that I place on the circuit.Below I have several design that i have tested.                                                                      Figure 1 : Sample block with no crack.                                                                       Figure 2:Sample rectangle with no crack.      Figure above shown rectangle and block which I created using Autodesk Fusion 360.This to minimize the computation progress ...
