I've been looking for details about how to constructing the stiffness matrix, though I know the general steps according to the [siggraph course](http://www.femdefo.org/).
I'm stuck here, how to co…

Hi,
I am trying to write a simple eigenvalue solver code in dolfin-x, but I have a problem in how to define a matrix as a PETScMatrix() and assembling the form into it. In the following, there is a p…

I'm using a symmatric matrix to perform a rotation of a 6x6 stiffness matrix like this:
```
SqrMat3 rotateY = BasicRotAIKy(phi);
SymMat randomRotationMatrix (6,EYE);
for (unsigned ri=0;ri

Hello All,
I don't have an issue with scikit-fem so much as I have a general question of use.
I'd like to take a beam, constrain one end then displace the other end, but not just in translatio…
