Re: [Getfem-users] modelling constraints

[Yves Renard]

Dear Daniel,

There is nt such an example. Particular constraints can be prescribed with a 
constraint brick (see 
http://download.gna.org/getfem/html/homepage/userdoc/model_constraint.html), 
which means that the index of degrees of freedom on which the constriaint is 
prescribed should be identified. It is possible to prescibre a degree of 
freedom with the pointwise constraint brick (see  
http://download.gna.org/getfem/html/homepage/userdoc/model_dirichlet.html#pointwise-constraints-brick)
 but it does not allow to link degrees of freedom from two different structures.

Yves.

Hi, 
are there some examples (e.g. inpython) where boundary constraints for linear 
elastic problems are modeled? 

e.g. 
- the classical "ten bar truss" problem. 
- single point constraints where nodal displacements are prescribed 
- multipoint constraints where some displacements/DOF are a linear function of 
other dof 

thanks
