However, care needs to be taken as this lowers the cell centre only and does not necessarily create a flow path for water into / out of the connection cell(s). Incorrect use of the "Z" flag can results in stability issues. <ins style="font-weight: bold; text-decoration: none;">For the 2012-05 release, it is possible for the user to set a maximum change in ZC elevation caused by the use of any "Z" flags for 2D SX links. This allows the modeller to automatically lower 2D cells within the specified limit, but flag an ERROR 2050 if there is a substantial change, which usually indicates there is something inconsistent between the 1D channel bed and the 2D topography.</ins>&lt;br&gt;</div></td> </tr> <tr> <td class="diff-marker"></td> <td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>If there is a inlet (vertical) structure that allows flow from the ground level to the pipe a pit structure should be used to represent this.</div></td> <td class="diff-marker"></td> <td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>If there is a inlet (vertical) structure that allows flow from the ground level to the pipe a pit structure should be used to represent this.</div></td> </tr> <tr> <td class="diff-marker"></td> <td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>|discussion_page=* [[Talk:TUFLOW Message 2050|Discuss Message 2050]]</div></td> <td class="diff-marker"></td> <td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>|discussion_page=* [[Talk:TUFLOW Message 2050|Discuss Message 2050]]</div></td> </tr> <!-- diff cache key mediawiki:diff:1.41:old-5272:rev-5452:wikidiff2=table:1.14.1:bc2a06be --> </table>
