Hi
I have exported from fluent in .encase format the different data files that correspond to different time instants. They are loading as separate files but i want to see the transient animation and the time averaged plots. For that i need to group them together in a single file. how can i do that in paraview?
thanks

Hi, I have shared the data via WeTransfer. There are 2 time steps for now. I need to group them so that i can do transient analysis in Paraview, like video or taking time averaged plots, etc. thanks!

Please share .scl files too

I have sent-please let me know if you can work with them

So you are working with separate file for each timestep ? Can you store them all in a single encas file instead ?

Like just copy paste them into a single file just i have done to sent them to you?

The simulation has generated seperate .encas files not in a single file

I’m afraid ParaView does not support opening multiple encas file and putting them together as multiple timesteps, it should be pretty simple to add though.

Means i have to add them externally and then open it in Paraview?

You have two solutions:
1. Configure your simulation to output a single file with multiple timesteps inside
2. Use another format that support reading as a file series in ParaView

Yea the first one involves re-calculating the solution again which will take 2-3 days. For the second one, i do not exactly know what reader to use to open these multiple files in Paraview.

Many, that depends on which format you can output/convert to tbh

I do not exactly have an idea-which format should i use to convert these .encase files for opening in paraview?
