| Summary | 0003866: patchFlowRateInjection + SprayCloud | ||||
| Description | Hello, When the patchFlowRateinjection is used in the SprayCloud, the Floating point exception always happens. After having debugged, I found the error is from the constructor of the class SprayCloud at the line of "averageParcelMass_ = this->injectors().averageParcelMass(); ". This line is called from the InjectionModelList.C file, and will return a value of mass/massTotal. However, When the patchFlowRateinjection is used, the constructor of patchFlowRateinjection will initialize the variable massTotal as zero (this->massTotal_ = 0.0; ) no matter which value of massTotal in the file sprayCloudProperties is used. Due to the zero massTotal, the Floating point exception happens when the expression of the "mass/massTotal" in the InjectionModelList.C file is evaluated. Could you please check it? Thanks a lot Edward | ||||

The problem is that the concept of an "averageParcelMass" based on total injected quantities makes no sense for an injection which simply creates particles at a rate proportional to the flow rate of the carrier. It really shouldn't be part of the injection model's interface. Fortunately, "averageParcelMass" is only actually used in one breakup model (ReitzKHRT), so it is only a very small subset of the functionality that remains incompatible with the patch flow rate injection. The code will now raise a "NotImplemented" error if this combination is requested. Considered fixed in dev and in version 10. https://github.com/OpenFOAM/OpenFOAM-10/commit/b2f0c22c5002ec162897665260a59dab987cc8e8 https://github.com/OpenFOAM/OpenFOAM-dev/commit/32bef33f4c03d734161546d910dfe937a71209cb |
