Patch antenna array memory problem
显示 更早的评论
I'm using Matlab 2020a. I'm trying to get the pattern of a single element in a patch array array (11x11). I get the "out of memory" error. Similarly, I can't get the antenna array pattern. Also "out of memory". I tried to change mesh configuration - no results. How solve it?
Error:
Out of memory.
Error in em.EmStructures/momsolver
Error in em.EmStructures/analyze
Error in em.FieldAnalysisWithFeed/pattern (line 177)
analyze(obj,frequency, parseobj.Results.ElementNumber, ...
Error in MikropaskowaPolistyrenMat3for (line 41)
pattern(ra,12000000000,'ElementNumber',cntr)

Hi,
The array configuration you are trying to solve is electronically large and is memory intensive. You can check the memory required by the following command:
memoryEstimate(antenna)
When I tried to compute the memory required for your current configuration it showed somewhere around 860 Gb, which is pretty high.
The only way you can reduce that is by tweaking the mesh and specifying a larger MaxEdgeLength, but the results are not going to be that accurate.
Hope this Helps!
