Hi foamers,

I am doing fsiFOAM recently. For the solid part, I need to simulate the deformation of a cylinder, so the traction on the interface between the fluid and solid should be non-uniform for the boundary condition. Just as the example in the tutorial.

boundaryField
{
    interface
    {
        type            tractionDisplacement;
        // traction        uniform (0 0 0);
        traction        nonuniform List<vector>
192
(
(27.7797 0.00151833 -0.134677)
(27.7826 0.00492101 -0.160698)
(27.7516 0.0112301 -0.160522)
(27.6904 0.0181003 -0.156203)
(27.5966 0.026365 -0.149447)...

There, the coordinates should be the center of each face, right? My question is how do I find those coordinates?

Any suggestions would be highly appreciated!

Thank you guys!
