Thanks Barry,
<div class="">That did it: I only had to specify KSPSetFromOptions() between KSPSetOptionsPrefix() and PCFieldSplitSetIS().</div>
<div class=""><br class="">
</div>
<div class="">May I ask you how does that work? What do you mean by “depending on where you set the options prefix they may have different results”? I could not find a clear explanation in the documentation.</div>
<div class=""><br class="">
</div>
<div class="">Thanks again for the help,</div>
<div class="">Simone</div>
