So, I have almost 500 .vtu files and .dat files from a computer simulation. It is a fluid simulation and I have a routine using ipython to plot each time stamp of the evolution of the fluid dynamics. The output, as I said, is given by two files: a .dat file and a .vtu file.
Therefore, my question is: how can I convert a vtu file into a jpg or png image?
(I opened a .vtu file from the output, but all that I receive was a white disk)
