Hi Tom-Robin, ParaView does not support having a time series of particles within a single csv file. You can have a file series of csv files as described here:
http://www.paraview.org/Wiki/ParaView/Users_Guide/Loading_Data Unfortunately, you will not be able to specify a time value in this case. ParaView will pick 0, 1, 2 etc. To be able to specify time values, you will have to use a format such as pvd or Xdmf. Of course, I just noticed that we have absolutely no documentation on the PVD format :-) We'll fix that. Here is some info: http://www.cacr.caltech.edu/~slombey/asci/vtk/ Xdmf is better documentation. Both of these formats support ASCII content. Xdmf supports having all of the data in one file although if you have thousands of time steps, the file may get somewhat bulky. -berk On Thu, May 8, 2014 at 10:59 AM, Tom-Robin Teschner < [email protected]> wrote: > Hi, > > I am doing particle tracking at the moment and I am visualise my results > with paraview.
