  3. I am running Nox Post-processing on a finished combustion solution in Fluent V 19.2. When I select the PDF mode to be Temperature/Species under the Turbulence Chemistry Interaction tab, and elect to use the transported variance equation, there is an instant SIGSEV error when the run is started. This used to work in V 17.2. What is the best workaround in current releases, and when will it be fixed?

      This combination of models (Temperature/Species PDF mode with transported variance) was not working in R 19.x. It is fixed in 2019R3. The current workaround for v 19.x and 2019R1 or new releases is to use either: (a) Use the temperature PDF mode or (b) Use the algebraic variance option if temperature/species PDF mode is selected
