Hi there,

I am still figuring things out in Paraview. I did a CFD transient simulation and exported it to EnSight Gold format (.encas), where each file represents a different timestep. The naming is the same, where only the ending of the file changes according to the timstep, eg: main\_0001.encas, main\_0002.encas, …  
I am now trying to import this to Paraview to make an animation of the change with time. When I open the files each timestep gets imported as a separate pipeline object into Paraview, and I cannot make an animation. What steps can I take to step through the frames and make an animation? I have seen many videos online to make animations, though none of which use .encas files…  
I have also tried making a .encas.series file as illustrated below, though that does not seem to work  
{  
“file-series-version” : “1.0”,  
“files” : [  
{ “name” : “main\_0001.encas”, “time” : 0 },  
{ “name” : “main:0002.encas”, “time” : 0.025 },  
etc…  
]  
}
