traction of a 3D cylinder OpenFOAM - Extend
 

Hello,
I am currently working with the OpenFOAM extend version.
I have a 3D cylinder which I want to impose a traction force. I have been trying to do by including or a displacement or a traction force. Neither one nor the other run. In addition I cannot check the traction in paraview.

I attach the file DU where we can change the parameters that I have said before.
Is there any suggestion?




FoamFile
{
version 2.0;
format ascii;
class volVectorField;
location "0";
object DU;
}

}

cylindertop

}

cylinderbottom
