Query Result as HDF5?

Hi there,

 

I want to export stress querrys with large data sets. Until no I use:

myModel GetQueryCtrlHandle myQuery

[...]

myQuery WriteData ...

 

This results in large files. Is there a way to export also compressed data formats like .hdf5?

I know you can export hdf5 directly with control cards when running the simulation, but is it also possible afterwards?

 

Thanks in advance and best regards,

Merula

    Hi Merula,

     

    How big are your data sets? I export my query results in hwascii format and the result files are rather small sized. I'm unaware of a method to export in compressed data formats, but if you find anything I would be interested as well.

    I think the 'WriteData' command always results in .csv format. I prefer to use a loop to handle the results:

     

    myQuery GetIteratorHandle iter

    for {iter First} {[iter Valid]} {iter Next} {

    lappend Datalist [iter GetDataList]

    }

     

    You are more flexible in handling the result format this way, since you can format the data before exporting it.

     

    Thanks,

    niwi
