Hi All, I am seeking some advice regarding matrix multiplication in scirun. I have performed some external simulations of electric fields and am using scirun for visualisation. So, what I have is an array of points and the accompanying hex definition file to define the mesh, the solution at the node points and the anisotropic conductivity at the node points. I have found that I can read in the solution and subsequently obtain the gradient of the solution at the node points. My question is, can I read in the conductivity matrix and multiply this by the array of gradients to obtain the current? The conductivity matrix is Nx6 (one row for each of the N node points) and, since the conductivity matrix is symmetric, has rows of the form a11 a12 a13 a22 a23 a33 Hence the current vector at any node should be the matrix-vector product of this matrix (expanded to 3x3) at this node and the gradient vector calculated at the node. Is such a manipulation possible in scirun? Thanks for your help, Peter Johnston. -- ------------------------------------------------------------------------- Assoc.
