How to access the state point document with the data

Hello everyone!
Does anyone know how to access the state point document “raw data file” with the results from the simulation?

Hi Eliahissa

From the screen shot it looks like you have a graphical user interface that wraps openmc and paramak code. So the behavior of raw data file button you have circled depends on the programming behind that user interface.

You can get the raw numbers for the mesh tally data by using the openmc python API. I guess you would need to find the statepoint file made during the simulation and be running linux to run openmc.

This last box in this example shows how to reading a statepoint and get a tally

    "This notebook allows users to create a simple geometry from a few different materials and plot the results of a 3D regular mesh tally applied to the geometry."

Thank you so much! I will try it right now!
