[Paraview] [EXTERNAL] displaying simulation time rather than time step

Thu Oct 9 07:12:21 EDT 2014

A similar question came up a few weeks ago and I posted this link
https://hpcforge.org/plugins/scmgit/cgi-bin/gitweb.cgi?p=pv-echam/pv-echam.git;a=blob;f=vtkJulianDayToTextConvertor.h;h=490320de30539ed88527ca79c53e2acc17264bf5;hb=HEAD
To a class which takes climate simulation time stamps and converts them from julian date to a string. This can then be viewed in the paraview gui as a time stamp with an arbitrary format – you can add the time as well as the date by some simple changes.

I have not used it myself for several years, but just copied the vtkJulianDayToTextConverter.* files and jdn.c into another plugin and tried them. Apart from one tweak because DATA/UPDATE_TIME_STEPS are now singular it compiled ok and is working as expected.

The class create a single text string in a 1x1 table and paraview displays this as an annotation.

Strike that last comment about Annotate Time doing the right thing. There are probably file formats that make the date/time string available, but I can't name one off the top of my head and you will still need to hook up the connection to the Text Source something like above.

I think that Sean is on the right track and suggest that a Python Animation cue is the way to go.

Attached is a state file to demonstrate. Load the state file in ParaView, open Views->Animation View and double click on the existing Python track to see the script that gets the pipeline time and feeds it into a text source for display. I've left the parts about reading the file and mapping the Animation time into the corresponding simulation time as an exercise to the reader.

Note: many time varying file formats produce the data time for you so this translation is unnecessary and the Annotate Time filter will do what you want it to.

Hi Sean,

Can we talk?  I’m not smart enough to understand your suggestion (hate it when that happens).

If I get something worked out, even a hack, I’ll post the solution back to this list.

Thanks!

Hey Phil,
You *might* be able to hack it with a combination of a Programmable Filter and a Python Annotation Filter.  Use the Programmable Filter to add a FieldData value to each time step that is a string with the appropriate date.  Then use the Python Annotation Filter to display the date as an annotation.

The first part is the hard one.  The Programmable Filter could either (1) read the file once to get all the dates, or (2) compute the dates using the starting date, the time step value, and Python's datetime module.

Thanks,
Sean

Phil,
I have no idea how to put out what you are asking for, but it is a really good idea.  If you don’t get an answer, be sure to write up a bug report/ feature request.

Subject: [EXTERNAL] [Paraview] displaying simulation time rather than time step

I would like to do something similar to the Annotate Time filter, but rather than displaying the time step number, I need to display simulation date and time.

I have a text file with the actual simulation date and time associated with each time step.  Here are the first few lines of that file

Time step   Time step output, Actual time
0               0.00,           4/1/2013 15:00
1               65.83,          4/1/2013 15:01
2               125.88,         4/1/2013 15:02
3               201.00,         4/1/2013 15:03
4               268.65,         4/1/2013 15:04
5               328.83,         4/1/2013 15:05
6               366.46,         4/1/2013 15:06

…

So, rather than Time: 0 at the bottom of the 3D window, I’d like to have 4/1/2013 15:00

Any thoughts / recommendations on how to accomplish this task will be greatly appreciated.

Thanks,
Phil
