[General] paraview animation

drudox · January 24, 2019, 04:53

Dear all, I have to make an animation of polymer rheology (deformation due to hydro dynamic interaction)

In order to doing this, I exported from the CFD (in House) code the polymer chain's beads coordinate written in VTK fortmat (POLYDATA) using Filter like glyph (for the beads) and tube (for the connection) I get a nice pictures of polymer in certain position.

I'm exporting this coodinate each time step of total 10 time step (just to try make a small animation), the file are named in a way that paraview recognized as time sequence (the end part of the filename is the time step) ,

But now I have problem related to the fact that the chain moves with the turbulent flow
so I cannot have a fixed area in which each time step i see the polymer change configurations! But this is what I need , there is some way to set the camera fixed with the chain and not with spatial coordinate ?

thanks in advance

If you have only 10 time steps, you can take screenshot of each time step as you like and then convert those images into animation using ffmpeg.

yes thanks but I solved ! paraview allow during animation settings to define the options CAMERA : Follow data , so regarding the polymer I'm ok .. I think I will open one other thread about flow field , how to select a given number of cell from a DNS stragged grid (cubic box with equally cubic cell)
