<p>Hi, all PETSc developer:</p>
Thank you for your great works. I have deploy my fvm code based
on the PETSc.<br>
It works well, and the results are beautiful. But I found a problem
that some of the <br>
functions, such as DMPlexGetSupport and <a
href="http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/DM/DMPlexPointLocalRef.html">DMPlexPointLocalRef,
are very expensive.</a><br>
It costs a lot of times if such routines are involved. Is there any
method one can use to reduce <br>
the time costs and improve the efficiency of the executable
applications?<br>
Thanks<br>
