May I ask how OpenMC can use a specified cell filter to draw the corresponding heat map
like this：
tally11a = openmc.Tally(name=‘cell11_a tally’)
cell11_a_ids = [cell.id for cell in cells if cell.fill == fuel]
cell_filter = openmc.CellFilter(cell11_a_ids)
tally11a.filters.append(cell_filter)
tally11a.scores.append(‘fission’)
