The calculation comes from the pressure and velocity data from the simulation using kSpaceOrder. The stresses have the dimensions same as (Nx,Ny). Now I need to use these stress data for the elastic simulation using pstdElastic2D.</p> <p>As I want to have the result for the entire space, I made sensor.mask=ones(Nx,Ny) as well as source.s_mask=ones(Nx,Ny) as I want to use the Sxx,Sxy, and Sxy (having the same dimensions). However, when I tried to run it, I got the following error: "The number of time series in source.sxx (etc) must match the number of source elements in source.s_mask" </p> <p>I checked the example_ewp_shear_wave_snells_law example, where tone burst were used for Sxx, Syy. If I use the toneburst, then it runs for me too, but how I can use the calculated Sxx, Syy, Sxy (obtained from kSpaceOrder) as an input of pstdElastic2D. What should be the dimension of those stresses? </p>
