long simulation time of a drone

Hello,

i am currently simulating a drone to study the radiation pattern of this drone with vortex waves.

I am using MLFMM to make the simulation time less.

Is there any better option to reduce more the simulation time?

Thanks in advance.

 

Best regards

    If your source is a plane wave with multiple angles, then MoM or MoM with Higher Order Basis Functions could be a better option. Multiple angles solves faster with MoM than MLFMM.

    Hello,

    i have to use vortex waves and that's why i have to use normal antennas instead of a plane wave.

    Is there something better to make it?!

    Could you please attach the cfx?

    Hello,

    unfortunately the model is to pig.

    You can upload the model and illuminate the plane with the sph file.

    The Distance is not a problem.

    Could you try deleting the mesh and uploading the unmeshed cfx? It's necessary to see your settings.

    You could use Large Element PO which will run very fast and use a few MBytes. 

    MLFMM, using a lam0/6 mesh, would be about 30 to 80 GByte depending on the number of processes and preconditioner.
