**Is your feature request related to a problem? Please describe.** dwsim.org describes 'Standalone Thermo' as one of the use-cases of DWSIM. Due to the nature of the binaries being compiled...

**How to call a function through Excel VBA?** For example I can call "CalcProp" function through Excel Worksheets, but can not call the same function in VBA. Is there any...

**Describe the bug** Dewpoint calculation fails for the PVF flash for PR, SRK, GERG etc **Expected behavior** Identify dew point temperature of -11 / -12 C'ish at 40 barg **Desktop...

bug

Right now DWSIM 6.6 supports three modes (type of specs) for PFR simulation: 1. Isothermic 2. Adiabatic (e.g. Adiabatic-Nonisothermal) 3. Outlet temperature (nonisthermal but rarely reflect a real case as...
