Maxwell 2D Parameters Post-processing during analysis Result Sometimes manual processing is very inconvenient. In this case, we need to use a macro method to solve the problem. Here we only propose a solution. If you have a better solution, please talk about it.
& M-S2 R-l s! D7 ^ 1. How to obtain the calculated parameter value
9 L1 [& O: S4 A5 A7 H + A6 | In 2D post-processing, you cannot directly call the variables in the pre-processing (currently I have not found a method to directly access the variables, please let me know), so you only have to find a way to get the current variable value, through File You can find that the initial. cn2 file contains information about the current variable value in each step of variable analysis. For example, the following content is from initial. cn2:
5 K $ R2 l8 p -? + S "s, M + d $ _) _ 9 h B _symtab & I #}; @ "V # V
Nthickness = 20
& S2 H + V % U3] E_symtab
8 U1 B, E! A # Z3 v $ s Here there is a variable named nthickness, so the following macro is to get the nthickness value from initial. cn2:
I @ # M # T! [1 E4 Q8 z5] Assign sparafile "Initial. cn2"
4 J "J6 l r$ r'e & M # I/B6 F ,[! N6 B0 P8 V3 H/z "V7 C & I

I have mentioned this in a previous post. Command For more information about macro usage, see the macro manual. Solution The result outputs a line of magnetic induction intensity curve, and all the results are stored in the result_linein.dat file, while the curve name is defined as the value of linein + nvalue, through this, we can easily distinguish the meaning of each curve. We need to observe the graph and use the plot directly. Program Open it. "? * @ # A # X % u &\
