Hi,
I was wondering if it is possible to specify two different sources of input to create a derived field. Currently with a single source, I have a derived field defined as:
def _HII_HFraction(field, data): return data["HII_Density"]/(data["HI_Density"]+data["HII_Density"])
add_field("HII_HFraction", function=_HII_HFraction, units=r"\frac{\rho_{HII}}{\rho_H}")
And I can access the total quantity in parallel
pf=load(file)
dd = pf.h.all_data()
dd.quantities["TotalQuantity"]("HII_HFraction")[0]
But I'm dealing with
pf1=load(file1) pf2=load(file2)
pf1 has the HI_Density field data and pf2 has the HII_Density field data. Is there a way to create a derived field and use TotalQuantity to operate on the data in parallel?
From G.S.
PS. I guess my alternative is to glue the two HDF5 files into one, but want to avoid it if possible.
