Simulates the propagation of waves from multiple transmitting elements.
Until this package gets registered, open the Julia environment from inside the package folder:
julia --project=.
using WaveSim
# Define simulation parameters (use many default values, see the WaveSimParameters struct).
sim_params = WaveSimParameters(
focus_depth = 0.03, # [m]
steer_angle = 10.0, # [deg]
aperture_size = 0.02, # [m]
);
# Compute focusing delay for the elements of the phased array.
trans_delays = WaveSim.delays_from_focus_and_steer(sim_params);
# (optional) Compute optimized "best" spatial and temporal parameters.
sim_params = WaveSim.autores(sim_params, trans_delays)
# Run the simulation.
images = WaveSim.wavesim(trans_delays, sim_params);
beam_energy_map, transmit_time_map = WaveSim.beam_energy_map_and_transmit_time_map(images, sim_params);
# Display results.
include("src/view.jl")
imshowall(images, beam_energy_map, transmit_time_map, sim_params);
# Save results.
include("src/save.jl")
saveall(images, beam_energy_map, transmit_time_map, sim_params, "images")
Visualize the wave propagating through space, over time:
Get a spatial heatmap of where the energy went:
Know the transmit time delay everwhere in space:
The code supports multi-threading, make use of it by setting:
export JULIA_NUM_THREADS=4 (or whatever number of cores your machine has), before starting julia
or start julia directly with:
JULIA_NUM_THREADS=`getconf _NPROCESSORS_ONLN` julia
