I was experimenting with Dealii examples and stumbled on some error I can not
find a reason for.
I modified the example step-36 by defining an area like a pyramid on top of a
truncated pyramid.
I constructed the truncated pyramid from 5 simplexes and top pyramid of 2
simplexes by merging
these 7 triangulations.
At running the program stops with the error:
./step-36.exe
Number of active cells: 224
Number of degrees of freedom: 327
[0]PETSC ERROR: --------------------- Error Message
--------------------------------------------------------------
[0]PETSC ERROR: Argument out of range
[0]PETSC ERROR: New nonzero at (3,3) caused a malloc
You are writing into a matrix entry that does not exist, i.e., that has not
been allocated in the sparsity pattern. Why this happens is difficult to tell,
but you ought to find out why your program writes into entry (3,3) of the
matrix, and why that entry has not been allocated before.
