Normalizing medium with respect to wavelength when simulating high freq. array

Hi,

I am trying to simulate RF data for an array with 10 MHz center frequency. However, I am not able to use a voxel size of lambda/6 owing to computational limitations (where lambda is the speed of sound in medium with f = 10 MHz). Is there any way to normalize the voxel space (which currently has dx = dy = dz = 200 micron) with the appropriate wavelength as obtained from the center frequency to better simulate the RF data?

Thanks,
Mahaan

I’m not totally sure what you’re asking. You can run simulations in normalised units, sure, but that won’t help you if the ratio of the total grid size to the grid spacing stays constant.
