Hi All,
This is maybe too general a question. My results showed in the attachment is the derivatives of the flow field, row is the x direction and column y direction. You see there are the signs alternating every grid point in the y direction. I used compact scheme to calculate the derivative. I want to ask what could be the reason for this kind of outcome. I know that dispersion error could generate some alternating signs along the y=0 line, for example. Thanks, Jo |
