problem with RBF (openFOAM-1.6-ext)
 
1 Attachment(s)
hi foamers.

i have a problem with RBF. i customized kinematicModel.H proportion to my case but patch is define to move did not move.my case is 3D.i refine mesh but not any different in results. output file for U for any time like that :

i attach kinematicModel.H .

Code:

    cylinder
    {
        type            movingWallVelocity;
        value          nonuniform List<vector>
120

i run any case 2D & 3D with RBF my patch dont any move. i ran tutorial movingblockRBF without error. why?
thanks for helping me...

i see tutorials movingblockRBF and see dynamicMeshDict file. by changing inner radius & outer radius & facial point solution get a error.
anyone know inner radius & outer radius & facial point in RBF(radial basis function) exactly refer to what?

I have the same confusion about RBF .
Anyone know inner radius & outer radius in dynamicMeshDict file refer to what?
Do you have the tutorials movingblockRBF? I also have the difficulties to read some code .For example,

W2Coeffs

{

radius 1.0;

}

TPSCoeffs

{

radius 5.0;

}

GaussCoeffs

{

radius 0.1;

}


The coeffs listed above refer to what?


Thanks a lot in advance!
