When you make your own solver, and you want all/the most of fields to resize.
node = hou.pwd().parent()
obj = node.simulation().objects()[0]
subDatas = obj.subData().keys()
exclude = ["Geometry", "Solver", "Visualization", "Forces", "SourceObject",
"collisionindex", "pumpindex", "init"]
fieldlist = ''
for data in subDatas:
if data not in exclude:
fieldlist += data + ' '
return fieldlist
If you write above on "Extra resize Fields" on Gas Resize Fluid Dynamic to resize fields created by smoke object,
you get:
collision pump temperature density source fuel vel tempdiv collisionvel burn divergence pressure sourceindex confinement sink heat
