Hi,
I have a problem on the work of sensors, I have create a time variating pressure source
source.p = 30 * sin(2 * pi * source_freq * kgrid.t_array);
The p_mask it's just a point in the center of the grid. And I try to record the variation of this source with two sensors put at the same x_axis of the source and one at y_source+1 and the second at y_source+100.
I use sensor.record = {'p'}; to record the evolution of preassure
But when I plot the result of the first sensor I obtain some time something totaly wrong , like a sinus curve but variating between 4 and -4, and some tine a sinus curve vevy between 25 and -25 but totaly with the wrong phase.
And for the second sensor it's wrost becouse he recrod somethong even when the whave the wave did not reach it, and the sinus curve viry between something like 1*e-3 and -1*e-3.
My grid is an 256*256 and teh space between point it's about 0.001 meter.
What have I done wrong?
Best regard
