HI Michael,
I’m not the original author of step-18, but I think that I’ve found some
sources that can explain both the construction of the non-normalised rotation
axis w and the angle θ calculation.
1. Axial vector ω (the non-normalised axis of rotation)
For this, I’m summarising the salient
Dr. Wolfgang,
Thank you for the reply.
So is your fine mesh a refinement of the coarse one? If not, you may want to

Yes, it is. But the "refinement" is done by the meshing software, outside
dealii. Is there any simplification possible in such a case?
Otherwise, I

Hi Peter,
Thanks for your reply. I have PBC in all the 3 directions ( I have included
the code snippet above for only 1 direction). In addition to this, I want
to apply compression in 1 direction.
I checked the constraints using
AffineConstraints::is_consistent_in_parallel() and it returned 1.
Dear all,
I am trying to modify my program in a way such that certain quantities are
only updated if the underlying triangulation object changes during runtime
(due to adaptivity). I want to call a specific member function of my Main
Class 'Solid' if this happens. (Solid is the class which

Dear all,
I want to save a coarse grid solution, load it and set it as the initial
condition for a finer grid simulation.
The code I have written is for non-adaptive meshes, the refinement is not
happening within the simulation. I wish to start the fine grid simulation
using a standalone fine
Thank you for the clear answer, I understand my mistake now, it is much
simpler like that.
