I noticed the new functions (Level 2) in ANSYS 2020R1 to increase the stability of VOF model, When I set everything well in ANSYS 2020 R1, and moved the case to run it on the ANSYS 2019 R3 version. The results in ANSYS 2019 R3 shows the convergence performing not as well as in the ANSYS 2020 R1. I checked the journal file in ANSYS 2019 R3 , which shows"Default context "constant-density-NITA" conflicts with at least one context from the case file and will be discarded." Could you help me to explain about this text? The details have been attached. Thanks.

Sounds logic that new updates cannot be applied to old release.
