Dear all,


I was wondering whether it is possible to directly post-process Time History data output with custom-written Python scripts?

What kind of format is the *T01 file? Is it a binary format (is the format known)?


A short synopsis of what I am working on is an automated peak detection method on certain Time History Output data.

I want to find out at which time a peak value occurs, and subsequently want to look up the Y-value at that same time for a different Time History Output.


If a script (different from Python) is available that can directly be applied to the *T01, then I am also happy.


Kind regards,

Hi George,


thanks for the response.

I get the point of reading the peak value from Hypergraph X-Y plot.


What if I do not want to use Hypergraph, but instead I want to use a script that directly processes the T01 file?


Or is there any easy way to process the T01 file, like...


def processT01(inputfile="runnameT001", param="IE"):

1= Load the T01 file

2= Read the values for the defined parameter, in this case "INTERNAL ENERGY"

3= Convert the values to a comma-separated value, e.g.

Time, IE

0.000, 3150.

0.100, 3155.

0.200, 3158.

Save in this format to a new file: "my_output.csv"


In this way I can further post-process the data.


I need to do this for multiple simulations, and for multiple time history output data per simulations (e.g. 5 springs per simulation).

That is why I want to automate this process.


Kind regards,

Hi Robbin,

The possible workaround for your need is:

You can plot in HyperGraph manually first time and then save it as Report Template. Next time, you can say "Open Report Template" and select a different T01 file. The process will be repeated for the newly selected T01 file. In order to get the curve data in csv format, you can use Export Curves option in HyperGraph.

I have made a simple recording of these steps which is attached along.
