when I run software, below message appears. "There is no reference pressure." Do you have an advice to solve it? Regards, Mahdi |
Quote:
It is just a warning message from the solver that initial pressure is not given. And solver takes care of that & calculates iteratively in next time step. You can ignore it. If you really don't want to ignore it you can define uniform pressure in Initial tab & Void Initial state > Pressure. If you are simulating no sharp interface case then in Initial Tab > Pressure > Hydrostatic pressure value takes care of that. Regards Jay |

Do you know that, how I can print stream line in flow-3d? |

There is no problem with mesh resolution !! Vortex shedding takes time for shaping it is not immediate. Try simulating for about 30s ... and do not care about the warnings that say flow is nearly steady.. |
