Thanks Barry, That did it: I only had to specify KSPSetFromOptions() between KSPSetOptionsPrefix() and PCFieldSplitSetIS().
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. Thanks again for the help, Simone On Apr 8, 2018, at 12:24 PM, Smith, Barry F. <[email protected]<mailto:[email protected]>> wrote: KSPSetFromOptions()
