[FLASH-USERS] visualizing polar coordinates

[Djibrilla Boureima, Ismael]

Hello All,


In case you chose to try yt, the following could help:


from yt.mods import *


# Checkpoint file or plotfile location:

CkptFile_location = '/location/to/your/checkpoint/file/checkpoint_hdf5_plt_cnt_0000 '


#Variable to plot:

var='dens'


apf = load(CkptFile_location)

sl=SlicePlot(apf, 'phi',var)
sl.set_window_size(14)


# sl.set_center((0.0,19.0)) # 19.0 is my Xmax/2.0
#sl.zoom(2.0) # This will hep zoom-IN;  change the 2.0 to anything you like

sl.set_cmap(field="dens", cmap='jet') #Pcolor style
sl.set_buff_size(2000) # Image quality
sl.save() # or sl.show() if your on a ipython notebook


Best


Ismael

I highly recommend yt, but you can do this in VisIt by adding a "Transform" operator to your plot then setting the options for the operator to do a "Coordinate" transform.  I think you want to go from "polar" to "Cartesian" coordinates in the Transform.

Hi Kevin,

In version 3.0 of yt it should "just work" to visualize polar coordinates from flash.

Does anyone know how to visualize FLASH results with polar coordinate (r, phi) using either visit or yt ?
