Got it, thanks for the heads up

Thanks!

Well that’s disappointing, i really tried optimizing it and it worked well on the few devices I tested (I have an iPhone 13 Pro that handles it well). I will see what I can do to make it more smooth.

And yes I am working on adding different kind of pec obstacles, dialectic materials and ohmic conductive materials.

The challenge is to keep the solver cheap while preserving reasonable accuracy.

May I ask what phone do you have ?

Thanks for the feedback:)
