9 months ago If you are using the to_global method on slices, you can use the fill parameter and set it to numpy.nan, e.g.:
import numpy as np
import fdsreader as fds
sim = fds.Simulation(".")
sim.slices[0].to_global(fill=np.nan)Does that solve your question?
Areas outside the mesh are labelled as nan. Here I can label "missing areas" with cmap.set_bad(colour='gray') in conjunction with plt.imshow. However, areas inside solids are saved as 0. If gas phase properties also have a value of 0, I cannot simply overwrite these positions with nan.
