I tried PetscViewerFileSetMode and use the "FILE_MODE_APPEND", but it seems that the file has been overwritten,too.<br>
<br>
I was not able to find any examples in tutorials, is there one using it?</blockquote><div><br>Here is an example that appends to a file.

You use a ViewerCreate() and then<br>
<br>
<a href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manualpages/Viewer/PetscViewerFileSetMode.html" target="_blank">http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manualpages/Viewer/PetscViewerFileSetMode.html</a><br>
<br>
to set append, and then FileSetName() to open the file.<br>

Hi,All,<br>
<br>
I tried to use PetscFOpen to write the numerical result to a file, and I<br>
would like to use the mode "a+" to add my result to the existing content in<br>
my file. However, whenever the new result comes out, it will overwrite the<br>
existing content in the file. Is there any problem here?<br>
<br>
Thanks a lot!<br>
<br>
Rebecca<br>
