Re: [deal.II] extrude triangulation with n_slices = 1

Greg: I decided to modify the code to adopt a p::shared::T model with METIS and realized anisotropic refinement doesn’t seem to work for this case either. The error comes from AffineConstraints’ unacceptance of any refinement cases that are not isotropic. The same error can be reproduced for m

Hi! I looked out for what you are suggesting, but I don’t understand. https://www.dealii.org/download.html Here I read that dealii version 9.4.0 is just for Intel macs (and for MacOs Monterey) Moreover on the guide for M1 mac installations it results that the only way to install the library is

Wasim, step-40 uses Q2 elements which means that you have 9 dofs/cell in 2D and for 32 cells in each direction (33+32)^2=65^2=4225 dofs. Best, Daniel On Fri, Apr 7, 2023 at 5:47 AM Wasim Niyaz Munshi ce21d400 < ce21d...@smail.iitm.ac.in> wrote: > Thank You, Prof. Bangerth. > I have one more d

I ran a problem with 2000*2000 cells (around 16M DOFs) on 16, 32 and 40 processors. It took 63 seconds on 16 processors, 74 seconds on 32 processors and is giving the same memory error for 40 processors. For 52M DOfs, I get the memory error for all the 3 cases. Regards Wasim On Thursday, April

Thank You, Prof. Bangerth. I have one more doubt about the output of step-40. For cycle 0, there are 1024 cells (32*32 mesh). So, we have 33 nodes each, along x and y. So, shouldn't the number of DOFs be 1089 instead of 4225? Regards Wasim On Thursday, April 6, 2023 at 11:27:32 PM UTC+5:30 Wol
