Dear deal.ii developers,
I want to model time-dependent small elastic deformations (step-18).
Inputs (like triangulation, B.C., etc.) are handled by ParameterHandler and
prm file.
In applying multiple Dirichlet B.C. by looping over
"VectorTools::interpolate_boundary_values"
for a 3D problem, I will apply a displacement vector <dim> with two
scenarios:
1) displacement {1,0,2} applies on direction 1 to 3 for boundary id=10;
2)displacement {1,0,2} applies only on direction 1 and 3 for boundary id=20;
As mentioned in documentation, I tried to make component mask for each
scenario by hand.
So, I defined two extra vector <bool> which indicate presence or absence
(being free dof) of displacement vector as below
a) [true,true,true]
b) [true, false,true]
But, I couldn't use them as input in interpolate_boundary_values (error: no
matching function for call to ‘interpolate_boundary_values)
Also, I couldn't find a matching function FEValuesExtractors::Vector for
these cases.
Thanks in advance
Amir
