How to modify the loaded model package data with pandas and run_modelflow??

[ArtCoff]

I loaded a model of an actual venue using the modflow.load method and read the data from its packages.
package.stress_period_data.df method is really readable for me.
how do I modify its data via pandas and run mf.run_model with the modified data?
For example, I want to use pandas to modify the flux data inside the WEL package in the image and re-run the model to output the data.

hey @GroundwaterSimulationOptimization

Here is something to get you started

If you've modified the wel spd as needed into a new variable new_spd, then adding it to the wel package would be something like this:

wel.stress_period_data = new_spd # beware this is overwriting the attribute but YOLO
wel.write_file(f ='cool_name.wel')

it should work with new_spd being a df or dictionary

if you save the wel pack with a different name don't forget to update the nam file
