Hi,
First all, I don't know if this is the ideal thread because I don't know if this is a bug, concept problem... The point is that I'm testing the cavitatingFoam case for a future work of diesel injector nozzle and when I run the case from tutorial without make any change it crash at Time = 2.08487e-05. Code:

Greetings Alvaro,
According to the output you've provided, you are using OpenFOAM 2.3.0, not 2.3.x. And you've mentioned that you executed one of OpenFOAM's tutorials, but you did not specify which exact one. Because in the folder "tutorials/multiphase/cavitatingFoam", there are all of these: Code:
├── les │ ├── throttle │ └── throttle3D └── ras └── throttle Bruno

Hi Bruno,
Sorry for my bad description. I'm a noob yet and I will try to be more rigorous next time. Returning to the case, I tested the RAS model and then LES model (2D), but now both run correctly. I just had to low the maxCo and maxAcousticCo. Now I'm trying out my own geometry and seem it works fine. regards, Alvaro |
