<p>Hi Randy,</p>
<p>I was about to email why it didn't work even after changing them
to PetscInt. Then I realise that ierr should be defined as
PetscErrorCode.</p>
<pre class="moz-signature" cols="72">Thank you very much.

Don’t forget that not all integers passed into PETSc routines are
64 bit.
<div class="">For example, the error codes when called from
Fortran should be defined as PetscErrorCode and not PetscInt.</div>
<div class="">It’s really good to get into the habit of correctly
declaring all PETSc variables according to the web pages, so
that you can easily switch between 32bit and 64bit integers.</div>

ok, I got it. Btw, is it advisable to change all integer

I'm using the standard<br class="">

Currently, I use real(8) for all real values. If I
