Dear all,

I have the following derived field:

h=0.702

@derived_field(name = "Name", take_log=False, units='g/s**3')
def _Name(field, data):
    temp = data["Mach"].copy()
    temp.fill(0)
    ind = np.where(((data['dx']*128*1000)*(1+z)*h<100))
    temp[ind]= 0.5*data["Density"][ind]*(data["Mach"][ind]*data["SoundSpeed"][ind])**3

    return temp

How to check that, how many cells with cell size less than 100 kpc (data['dx']*128*1000)*(1+z)*h<100) ?

thankyou

Reju Sam John
