In some cases, I obtain non-physical solutions (for example, negative pressure). Can I use <code data-start="236" data-end="264">SNESSetFunctionDomainError</code> in this case? I tried, but I don’t fully understand how it works with NEWTONTR.</p><p data-start="348" data-end="371" style="margin: 0px;" data-mce-style="margin: 0px;"><br data-mce-bogus="1"></p><p data-start="348" data-end="371" style="margin: 0px;" data-mce-style="margin: 0px;">Thank you in advance</p><div><br data-mce-bogus="1"></div><div><div>best regrads,</div><div>Ali ALI AHMAD</div></div></div></body></html>
