Hi,
when I changed my global.F to global.f90, I was told that
PETSC_COMM_SELF, PETSC_NULL_INTEGER and PETSC_NULL_CHARACTER does not
have a type.
I declare
MPI_Comm PETSC_COMM_SELF and it works
So, what about the other 2? You mention to use
integer NORM_MAX
parameter NORM_MAX=3
What values
Hi,
My original matrix is stored in Ellpack-Itpack format, which is used by
the NSPCG solver. I have problems when I insert the values of the matrix
into a PETSc matrix. I guessed I made some mistakes but I can't find
where during debugging. So I intent to just convert from the

Any perticular reason why you keep using .f90 suffix even though I've
recommended using .F90 suffix [for preprocessed free form] a few
times?
I was told that PETSC_COMM_SELF, PETSC_NULL_INTEGER and
- make sure the input to MatCreateSeqAIJWithArrays() is correct as per
the example in the manpage
- run it in the debugger to determine the actual cause of the problem

Hi,
Guess I'm too used to typing .f90 ;-) I've changed it to .F90
before but perhaps at that time the error I got didn't disappear so I
didn't bother after that. I'm working in windows so I thought the
capital letter doesn't really matter. Moreover, .f90 also works with my
ifort in

I'm sorry - but you can't keep silently discarding the sugestions we
make and keep
Hi Satish,
I am sorry if I have made you angry. I may have missed out some
important points which you tried to highlight. I was converting several
of my .F fixed format files to .f90 (or .F90) free format and some files
which don't need declaration of PETSc type variable worked while some
I would like to define a class with a matrix as an member:
class Foo {
public:
Mat A;
};
I would expect that when an instance of Foo is created, A should be
initialized, just as it would be if it were declared as ordinary variable in
C:
int main (int argc,char **args) {
Mat A;
...
Mat is just a typedef for a pointer, so NULL initialization is correct. You
should put a call to MatCreate() in the constructor if you want the object
to be initialized.
Thanks,
Matt

If you get errors with the recommended model - you sould report the
erros [not silently try something else - and then report erros with
this something else]
I can't help you anymore unless you can report problems with a
