[deal.II] Debug error in Kelly Error Estimate function using parallel distributed vectors

Hi, I have just written a plan vanilla interface to call the Kelly Error Estimate function passing a parallel distributed vector as input vector type. But strangely enough when I run on MPI on multiple procs in debug mode, I get the following error: ---

Sir The Issue 6158 and 6159 have been opened for the proposed functionalities. Tell you if you have any thought. By instruction, it's actually more for the testing. Maybe I will just follow how the other functions are tested. By the way, I am at UC Berkeley leading an open source group project

Weixiong, Yes. It then allows non-uniform slicing along z-axis. Great. Yes, please do submit a pull request for this function! (And let us know if you need help figuring out how to create pull requests! I know we have a how-to file somewhere, but I forgot where exactly it is. Someone?)

Sir, Yes. It then allows non-uniform slicing along z-axis. Also, I am wondering if you guys are interested in making triangulation based on a basic one for repeated structure as shown in the attachment. I have to do this for my project but didn't find a function so I did something like copy->s

Hi, I found out there is not a function for extruding triangulation by exact position of cell vertices along z-axis. So I wrote a piece of code by modifying GridGenerator::extrude_triangulation. The attachment is an example of what it does. Did for my own needs. Just wonder if I can contribute

Re: [deal.II] Reason for SolverGMRES being slower in parallel?

I wish I can only deal with small problem, but that is only a test problem and I guess we need to use this code to compute much larger 3-D cases. Now it is too slow so I cannot test any larger cases than 400k dofs. I tried 400k dofs, still, 2 cores are slower than 1 core. The weirdest thing is t
