Error 37356 and Error 2580 MLFMM

AGirlHasNoName

Hello,

 

I have modeled a 10x10 array of microstrip patch antennas. I want to use the MLFMM solver to check the radiation pattern of this array. In order to do that, I first selected the 'Solve Model with multilevel fast multipole method (MLFMM)' option under the MLFMM/ACA tab of the Solver Setting. This resulted in error 37356, which says that DGFM and MLFMM cannot be used together. Therefore, I disabled the DGFM solver and then checked the MLFMM solver only. Now I am getting error 2580, which says that 'No special Green's function may be activated with the MLFMM'.

 

Where am I going wrong? Please let me know the correct way to use this solver.

 

Thanks in advance.

The Planar Multilayer Green's function is used to model your substrates and MLFMM is not supported together with the Green's Function.

If you want to use MLFMM, you would have to use a finite substrate instead of infinite.
