I am trying to analyze this simple diode circuit by hand, but I can't seem to get too far.

^{simulate this circuit – Schematic created using CircuitLab}

Using circuit lab, it is evident that current will flow through both diodes, which makes sense to me conceptually, however, trying to analyze using the Constant Voltage Drop model results in an unsolvable circuit.

^{simulate this circuit}

I have tried to use superposition, nodal analysis, and just KVL, but I can't seem to figure out how to solve this circuit.

Help would be greatly appreciated!

The circuit as shown is not viable - or you could analyze it in two phases, if you must:

Phase 1:

Fig.3 in datasheet) before the current exceeds absolute maximum ratingPhase 2.a:

If D2 burns outand becomes an open circuit:_{out}as D2 is now an open circuit_{out}=0 VoltsPhase 2.b:

If D1 burns outand becomes an open circuit:_{out}= V1 - V_{D2}=~ 4.4 VoltsThen there are the possibilities of D1 or D2 burning out to become short. That resultant analysis is left for you to do :-)
