<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt"> We were missing a Fortran stub in the code. You can either apply the attached patch or use the git branch barry/add-pcfieldsplit-getis/maint for the missing functionality. The
fix will also be in the next maintenance release of petsc-3.10<br>
<br>
Please let us know if there are any difficulties.<br>
