[petsc-users] Issue about matsetvalues when turn off debugging

[Gavin Ge]

Thanks Barry. The problem is that the debugging couldn't detect any problem with the debugger. The crash only show up when debugger is turned off.

A segmentation violation error jumps out when I set value for the very first element in the matrix. There is no problem for me to run the program when turning on the debugging option. I just want to tune this for better performance. Or is it better to turn on the debugging option? Could anybody help me with this? Thanks!
