SWHS: Difference b/w Stable and Manual: Match output of IM2

[smiths]

Issue #523 has far too much going on to keep track of all of the details. This issue (and several others) highlights one specific difference between Stable and Manual.

• Missing information for the output of IM2 (non-trivial)
  Stable:
  
  Manual:
  

IM2 has been updated in the stable (Drasil) version:

Unfortunately the updates still don't entirely match the manual versions. The following changes still need to be made:

• The Equation doesn't match the manual version; it should have 3 cases (not 4)
• The note should contain the following bulleted list (ideally displayed as a bulleted list for ease of reading/verifying):
  • T_W is defined by (IM: eBalanceOnWtr).
  • The input constraint Tinit ≤ T_P^melt comes from (A: PCM-Initially-Solid).
  • The temperature remains constant at TmeltP, even with the heating (or cool-ing), until the phase change has occurred for all of the material; that is as long as 0 < ϕ < 1. ϕ (from DD: melt_frac ) is determined as part of the heat energy in the PCM, as given in (IM: heatEInPCM).
  • tau_P^S is calculated in DD? (needs to be added)
  • tau_P^L is calculated in DD? (needs to be added)
