Request: PropsSI Inputs of D and Q

[dansteingart]

it would be great if PropsSI could take a D and Q input to return values. Current I can hack it by reversing over a range of P,T,H or S, and matching against D for a given Q, but it would be great not to have to do that.

e.g.

Rather than

D3 = 1/0.845
Ps = linspace(1e5,3e5,500)
Ds = PropsSI('D','P',Ps,'Q',1,'water')
DifD = min(abs(Ds-D3))
DifDS = list(abs(Ds-D3))
ind = DifDS.index(DifD)
P3 = Ps[ind]

D3 = 1/0.845
P3 = PropsSI('P','D',D3,'Q',1,'water')

Thanks in advance. I know the former example could be more pythonic, but the request still makes sense IMHO,

Can be done I think. In fact I think it is already possible at the lowest level but not currently at the high level. I can make that change.

@ibell many thanks!
