Dear all,
I was trying to install dealii version 9.0.0 on department cluster using
candi,
git clone https://github.com/dealii/candi
cd candi
./candi.sh
--platform=./deal.II-toolchain/platforms/supported/linux_cluster.platform
but I got the following error (it worked well for the installati
Thank you, Wolfgang, for your suggestion. I've read step-11 tutorial but I
still can not figure out what kind of constraints I can impose in my case.
Here is a picture of a void with enriched nodes. Blue triangls are enriched
with Heaviside function, red rectangles are zero degrees of freedom.

However, the errors appear as shown in the picture.
It seems to remind me that UMFPack is not installed.

So I get a singular matrix with zero degrees of freedom inside voids.
For this system to be solved I should eliminate rows corresponding to
zero degrees of freedom

Dear Colleagues,
I am writing to bring to your attention the open source beta release of
DFT-FE. DFT-FE is a real-space density functional theory code based on
adaptive finite-element basis (using the deal.II framework) for
ground-state pseudopotential and all-electron calculations (including

Hi!
I'm trying to implement XFEM method for elasticity problem with voids. I
use FE_Collection:
fe_collection.push_back (FESystem (FE_Q(1), 1, FE_Nothing(),
1));
fe_collection.push_back (FESystem (FE_Q(1), 1, FE_Q(1), 1));
Triangulation remains always unchanged, I do not cut voids in the mesh.
Dear Prof. Bangerth,
Thank you very much for your reply! Apologies for the ambiguity. What I

that, as you correctly pointed out, the jump in the gradient should equal
