Hi
I created a pcb antenna by antenna toolbox. My purpose is to optimize antenna geometries, but the current simulation lasts too much.
So I'd like reducing the substrate automatic mesh done by Matlab, I'm trying:
d = dielectric('FR4');
mesh(d,'MinEdgeLength',0.03/10);
But it doesn't work. what is the correct function?
Thanks,
Regards

mesh function does not operates on dielectric object.
If you have your antenna object ready, say the object name is ant. you can try the following code:
mesh(ant,'MaxEdgeLength',0.3); then use memoryEstimate(ant) to check how much memory it may require to solve this problem.
if your antenna object is pcbStack, then you can also specify MinEdgeLength property in mesh.

Hi,
I understand that you want to mesh the dielectric manually to improve the speed of execution.
Try changing the configuration settings of the mesh to manual by using the following command:
meshconfig(d,'manual')
After you do this, run your meshing command:
mesh(d,'MinEdgeLength',0.03/10);
Please refer the following link for more information on the “meshconfig” function
