Hi all,
I am trying to add some off-diagonal value to a fvMatrix instance, say, setting a[i][j] = 2 (which is zero before). And i , j are the row and col, respectively. So what I am not sure about is how many things I need to play around with? Is it enough to modify only lower() ( or upper() ), lowerAddr() and upperAddr()? A further question is if I need to frequently insert values to the list or field above. What is the computational efficient way to do that? Btw, I don't need to worry about the boundaryCoeffs and internalCoeffs. Thanks in advance. |

Do you find the answer ? If yes , Could u explain to me ?
I need to modify the matrix coefficient with cyclic boundary which is not implemented for blockmatrix in foam ext-4.0 . But I do not know how to deal with it . |
