Dear all, I have a flux vector f and a vector t for local time step. Both of them are global vectors.
And I want to update the flow variable vector x in explicit way x^(n+1) = x^(n) - t*f here t*f is each t's component multiply f's component. I searched the manual of petsc and find no useful information. Can anyone tell me how should I do t*f efficiently? Yours Gong Ding
