first of all congratulations for you very good job and many thanks for
We're trying to evaluate (my colleague is in copy) the centrifugal stress
and deformation of a rotating lamination, but we can't figure out how to
express the forcing term as a function of x and y.
Except for that, the LinearElasticity2d example fits very well.
The centrifugal force per volume is expressed by:
f = Vector (k*x , k*y, 0)
We tried to declare this term as a function, using both $X,$Y and simply X,Y,
F[Slab] = Vector[k*$X, k*$Y, 0 ]
but the solver puts to 0 all the terms multiplied by a coordinate.
We also tried to consider f as a field coming out of a potential, and to
integrate this "mass" potential at a time with the integration of the main
It looks terribly trivial..I hope it is.
Thanks in advance for you help. Best regards.
