Hi guys,
I am new here ! I need some help ! the problem in creating voxelPlot.h5 stucks on me. I don’t know why the “voxelPlot.ppm” and “voxelPlot.png” could not be created when running.
and the plotting part is below:(sorry ,maybe the problem is easy ,but I still need your help !!! )
#-----------------------------------------------------------------#
Instantiate a Plot
plot1 = openmc.Plot()
plot1.filename = ‘materials-xz’
plot1.basis = ‘xz’
plot1.origin = [0, 0, 0]
plot1.width = [7.2135, 360]
plot1.pixels = [1000, 1000]
plot1.color_by = ‘material’
plot2 = openmc.Plot()
plot2.filename = ‘materials-xy’
plot2.basis = ‘xy’
plot2.origin = [0, 0, 0]
plot2.width = [7.2135, 7.2135]
plot2.pixels = [1000, 1000]
plot2.color_by = ‘material’
plot3 = openmc.Plot()
plot3.filename = ‘materials-yz’
plot3.basis = ‘yz’
plot3.origin = [0, 0, 0]
plot3.width = [7.2135, 360]
plot3.pixels = [1000, 1000]
plot3.color_by = ‘material’
plot4 = openmc.Plot()
plot4.type = ‘voxel’
plot4.filename = ‘voxelPlot’
plot4.origin = [0, 0, 0]
plot4.width = [7.2135,7.2135,360]
plot4.pixels = [500,500,500]
plot4.overlap_color = ‘blue’
plot4.color_by = ‘material’
Show plot
plots = openmc.Plots(plots=[plot1, plot2, plot3, plot4])
plots.export_to_xml()
openmc.plot_inline(plots=(plot1, plot2, plot3, plot4))
#----------------------------------------------------------------------------#
the above is the plotting code and the ERRO IS :
