Hello
Is it possible to useHello
Is it possible to use openFoam to solve point implicit schemes? I want to solve A_i*U_i = B_i, over all cells. A_i is a 6*6 matrix. The coupling between the cells is brought about by the way B_i is computed. Is it possible to solve this on openFoam? regards Srinath |

Hello Srinath,
Yes: make a Hello Srinath,
Yes: make a loop through all cells, in each cell make a 6x6 dense matrix and invert locally. There are other ways as well, but this is easiest for the moment. Enjoy, Hrv |

Hello Hrvoje
I need to makeHello Hrvoje
I need to make a 5*5 matrix(not 6*6 sorry for the typo) The entries will be functions of u,v,p etc. So do you suggest i just define a new class, for any general square matrix, and write my own Gauss Siedel routine? I think the volTensorField is restricted to a sz of 3*3 Regards Srinath |
