Jan Stránský requested more information:
Hello,

> I am trying to apply DeadWeight on the tire to apply gravity force.

I will have a look. Is the tire loaded by a car? Then I think the dead
weight does not make much sense and an external load to its center
should do the job..

> And is it possible to apply constant pressure on the surface of the
tire to represent the internal air pressure of tire? I think
ConstantSurfaceLoad is suitable for this purpose but using
ConstantSurfaceLoad causes the same error as the DeadWeight above.

> I am also trying to apply force or torque to rotate the tire at
constant rotational velocity. Then is it possible to apply additional
force on the tire made by FEM mesh by Yade’s module like
O.forces.addF()?

not sure, I am a afraid that not.. maybe the torque can be applied in
Yade and according to the rotation a boundary condition of some nodes
may be updated.. will have a look, too

Concerning AttributeError, the problem is that I implemented only loads
which I used for the examples, I will add more of them..

Please describe here or send me email describing more in detail what you
want to simulate, I will try to add a basic version of it

cheers
Jan
