[petsc-users] [petsc-maint] error message from GDB

[praveen kumar]

Thanks Matt. I ran with -start_in_debugger and fixed the error. The code is
running but I can't figure out why the results are wrong when compared with
serial code. if you get time, please go through the code. it is a simple 2D
conduction code and I’ve employed DMDAcreate2D.



Thanks,
Praveen
