<div dir="ltr">Dear all,<br><div><br></div><div>I am trying to plot and make movie for the NSNSTOHMNS Gallery example using the support scripts provided. On using the VisIt support scripts as given in the example, I do get some figures named [rho_000000000.png, ... , rho_000000231.png], but they are all usually black screens or look like tv white noise.</div><div><div></div></div><div><br></div><div><br></div><div>Details of the simulation:</div><div>I ran it on a cluster with 8 cores.</div><div>My run data for mp_Psi4_l2_m2_r300.00.asc and rho.xy.h5 and the sample Results given in the gallery example are of the same order of magnitude(although not identical). So I doubt any problems on the data generation end.</div><div><br></div><div>I am using VisIt version 3.0.2 and FFMPEG version 4.2.1, and am loading python/<a href="http://3.7.3." target="_blank">3.7.3.</a></div><div><br></div><div>I get these when I run the command visit -cli -nowin -s <a href="http://rho.movie.py" target="_blank">rho.movie.py</a> </div><div><br></div><div>
