Open snapshots automatically

Hello all, I did not found topics on this, sorry if i missed some post. In our research institute we work some years now with CE-QUAL-W2 with very good results. We use v3.1 and we explore the results usually as time series and profiles but we wanted to explore the snapshots to get visualizations of hydrodynamics (velocities) or water properties (as map or dam profile to see what is happening in all the water body). We get the snapshots to work (they are saved to the file at the right frequency and right segments) but do not know which software may be used to open the file and produce images. Since doing it by hand (with all the segments, properties and instants and put it in surfer for instance) make it impossible… So my question is how to open snapshots automatically? Is there any software to do that? W2i? if yes, How to do that? Thanks a lot for your time. Best regards, David
