I am trying to use PetscOptionsGetString to retrieve the value of an option in the options database, but the value returned in the last argument indicates the option was not found. In the attached code (a modified version of ksp example 2), the string "-ksp_pc_side" is passed in as the argument name. If I run the code as<br>
<br>
./jc2 -pc_type ilu -ksp_pc_side right<br>
<br>
I get the output:<br>
<br>
option -ksp_pc_side was found<br>
<br>
from line 71 of the file. Petsc does not complain of unused options when the program finishes. Am I using this function incorrectly?<span class=""><font color="#888888"><br>
