   Hi,

   I want to run a simulation for temporal US propagation in a 2D (or 3D) domain, where multiple US point sources act as time varying pressure sources and each of their (distinct) source waveforms are given as a vector (of the same size as kgrid.t_array ---- this can be enforced by padding zeros).

   From my understanding, the example:
   http://www.k-wave.org/documentation/example_tvsp_transducer_field_patterns.php can simulate the similar problem, but all waveforms in this example have to be the same. I want to simulate the case where each point source produces a different pressure waveform.

   Yours sincerely
   Kevin

   Hi Kevin,

   I'd suggest having a look at the new kWaveArray class. One of the examples included does exactly this.

   You can also do this with the regular k-Wave sources by defining source.p as a matrix with the same number of entries as source grid points, it just takes a bit of accounting to make sure the correct source is assigned to the correct physical source.

   Brad.
