Hi,

I followed the instructions given in the userguide to run the tutorial problem(lid driven cavity flow) using a linearupwind(after modifiying the actual linear scheme for interpolation) scheme but the run gets killed with the following message "attempt to read beyond EOF". Can anyone let me know what this means and help me to implement the second order upwind scheme.

Hi there,

The following should work:

Code:
div(phi,U)      Gauss linearUpwind Gauss;

I believe the correct syntax is

Code:
Gauss linearUpwind phi
It needs the phi (flux) field to decided which direction is 'upwind' of the cell in question and generate the linear operators accordingly.
