Hi Tom-Robin, The values in the csv file needs to match the time values (not indices) reported on the information tab of the reader. There should be a table that lists time index, value pairs. Best, -berk On Wed, May 21, 2014 at 4:46 AM, Tom-Robin Teschner < tomrobin.tesch...@yahoo.de> wrote:

wow, thanks a lot for this! I am on a report deadline at the moment but will try it afterwards. I guess the easiest way is just to write integers (1, 2, 3 ...) as the timesteps to the cgns file which should make the mapping work without problems. In any case, I will fiddle around a bit with what

OK try this. Apply a Programmable Filter to the csv file. Turn on advanced properties on that panel and use the following scripts: Script: oi = self.GetOutputInformation(0) ut = oi.Get(vtk.vtkStreamingDemandDrivenPipeline.UPDATE_TIME_STEP()) t = inputs[0].RowData['t'] output.RowData.append(numpy.

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.

Hi,  I am doing particle tracking at the moment and I am visualise my results with paraview. I have a 3D Navier Stokes solver from which I get a CGNS file with the flow solution (for example velocity and vorticity in x, y and z) and I also get csv file where I store position of particles, which
