hi everyone, I want to define a time-change acceleration in sloshing movement. And maybe Fvoptions is a good way. Similar with tanksloshing3D6dof case in interDyMFoam. I want to define a acceleration term in non-inertial reference frame in interFoam. But I can not read the acceleration-term.dat using Fvoptions due to the formate of file.
So my question is : 1、Is there anywhere tell the formate of tabulatedaccelerationsource. 2、otherthan fvoptions, is there any good method to achieve non-inertial reference frame in interFoam. (I have try to added a "acc" just in the Uequ ,but the alpha.water does not change with "acc") thanks very much for any advises or help. Usage Example usage: \verbatim SBM { type tabulatedAccelerationSource; active yes; tabulatedAccelerationSourceCoeffs { timeDataFileName "constant/acceleration-terms.dat"; } } \endverbatim heng Jin OUC |

1、Expected a '(' while reading Tuple2, found on line 2 the label 0 2、wrong token type - expected Scalar, found on line 2 the punctuation token '(' |

Have you solved the problem? I am adding a direct force immersed boundary method into pimpleFoam, if I add the extra force from solid in the momentum predictor step, it can run but the results are wrong. I think I should add the force in pressure iterative step, because the force is chaging in every step. Thanks. |

Hi Shuo, Have you solved the problem? I am doing the same thing for IBM, but the results are so dependent on the Number of Piso loops. I think something is wrong with the way I am imposing my force in pressure piso loop. So can you please share to me your experience? Cheers, Mohammad |
