Creating and plotting grid in supernova/hydrodynamics example

[dnrgodilano7]

Hello and good day. We were trying to run supernova_grid.py and we are having this error on the plot_grid function:

   Grid.create deprecated, use new_regular_grid instead
   Grid.create deprecated, use new_regular_grid instead
   Traceback (most recent call last):

      return new_quantity(self._number[index], self.unit)
   IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices

on another note, is it possible to use supernova_grid.py to the output of molecular_cloud_collapse_with_sinks.py if we detect SN candidates in longer timescales by using the candidate SN output as initial condition to supernova_grid.py?

Thank you.

dear Nico,

I'll have a look at the ..._grid.py function to see what is wrong. regarding your second question,: I am not sure that that would be the best solution, but in principle what you suggest is possible. i would simply make a contour plot in pyplot, or convert it to an image.

cheers, Simon
