wetcoil.mo: TADP out of bounds when simulated with JModelica

[ThibaultMarzullo]

The current implementation of SOM3 crashes because the value of TADP drops below the lower bound. The error could be related to the MBL.

Dymola:

The simulation works flawlessly.

JModelica:

The simulation crashes before completing the first step. The log gives a warning and an error: 1) mod.system3CAV.sinSpeDX.dxCoo.wetCoi.appDewPt.m_flow_nonzero becomes zero, even if I manually set up a nonzero Mdot in the .mo file. This leads to a warning because of a division by zero. 2) mod.system3CAV.sinSpeDX.dxCoo.wetCoi.appDewPt.TADP decreases until it breaks a lower bound. The simulation crashes afterwards.

Debug

• [x] review changes to the dxCoo model, revert if necessary
• [ ] update HRG's fork with the upstream branch
• [x] test the dxCoo model without SoEP, in Dymola
• [x] test the dxCoo model without SoEP, in JModelica
• [x] check if this is due to a coil freezing

[ThibaultMarzullo]

The DX coil model can be abused in a simple test case and still works well in JModelica.
