Hello researchers, I generate 20 VTK files every 0.0001s. However, when I import them into Paraview, I find that the trend of radius variation is unreasonable (Fig. a). The correct trend is shown in Fig. b. Is there any way to solve this problem?

Also, I have another question. The animation runs too fast, and I want to slow it down. How should I do this?Thank you very much.

I do not understand your first question.

Use the TimeManager and increase the number of frames.

Your file numbers are interpreted as a sequence by ParaView. Rather than generating the files with the radius in the name, number them sequentially in the order you want them.

One possible solution is to determine the sequence of files in a JSON-based metadata file, like the one attached below, and then load this metadata file.

I understand what you mean, and I have succeeded. Thank you very much.
