Hello everyone,

I tried my best to simulate a 4x1 patch antenna array at 2.45 GHz, using the antenna array designer app but I couldn't. My laptop stopped working and I couldn't even move my cursor. My laptop is i7 7th generation and has 8 Gb RAMs.

So, is it my problem, or the app can't handle a large number of elements?

Thanks.

Hello,

The lack of response and progress is due to the large mesh. The structure is discretized into triangles (for the surfaces) and tetrahedra (for the volume) before being solved. If the mesh becomes very large, this will impact both the amount of memory (RAM) needed as well as time to compute the solution. To work around this, here are a couple of suggestions:-

Prior to running any analysis, use the memoryEstimate function to get an estimate on the RAM needed for solving at a particular frequency. Use help to learn more about this function.

help memoryEstimate

2. Manual meshing is also an option. To know more about it , you can visit the documentation link of meshing.

Hope it helps
