Hi Jean-Paul, Thanks for your help. My program failed to compile, so I didn't run it and get such an assertion. I see that the un-supporting of hp::DoFHandler for parallel distributed calculation in hp namespace. Thanks! Regards, Jack 在 2017年5月15日星期一 UTC+8下午10:27:22，Jean-Paul Pelteret写道： >

Dear Jean-Paul, If I did correct, first I call "cmake ." and then "make run ./step-42 p1_adaptive.prm" and did not use "make". With these changes, it did not work again. Thanks, Ben On Monday, May 15, 2017 at 3:27:29 PM UTC-5, Jean-Paul Pelteret wrote: > > Dear Benhour, > > I think that you mus

Dear Benhour, I think that you must have misinterpreted what Daniel suggested. If I run ./step-42 p1_adaptive.prm > then this tutorial works fine for me. If I run "make run" then the (unusual) error message appears for me as well. Regards, Jean-Paul On Monday, May 15, 2017 at 7:30:25 PM UTC

Dear all, I’m trying to using hp::DoFHandler to solve my problems. It seems that this type of dof handler does not work for solution transfer during parallel distributed computing. So is there any way to transfer solution after refining and coarsening of mesh when using hp::DoFHandler?

Dear Benhour, I would suggest removing the CMakeCache.txt file and CMakeFiles directory (both located in the tutorial/build directory). Then rerun CMake before trying to build the tutorial. It might be that there are some stale configuration settings that need to be updated. Regards, Jean-Paul
