Reading .dac time step information

I am trying to look at head data from multiple time steps in the model results .dac file.  I have external code to post-process ASCII .dac files, but was hoping to use an IFM plug-in to process the binary data.  I am working with large binary .dac files (up to 250MB), and reading the binary data should be much faster than dealing with ASCII versions of the results.  Is there an IFM function to set the "current" time step in a .dac file to read the stored head data, or any other way to read through the stored head results? 

I looked through the IFM API index (http://www.feflow.info/html/help/default.htm?turl=HTMLDocuments%2Fifm%2Fifm_api%2Fapi_index.htm) and I suspect the answer is no.  The API appears more geared to run-time calculations. 

Unfortunately there's currently no such option - so the only way is by using the ASCII dac file.

Dear all,
I was wondering if there has been any update to changing the "current" time step for reading .dac files via the ifm in Feflow 7.1?

This would be a really helpful feature to quickly compare different model variations.

Thanks,
Lennart

The Python API allows you to make comparison between dac-files. Please find a sample snippet here:

Thank you Björn, these two ifm functions are exactly what I was looking for!
