An example of a self-intersecting region is shown below with (the blue circles highlight the problem areas), click on image for a larger view.<br>

|suggestions=Check region perimeter does not cross or snap onto itself. To help identify the problem, the followfollowing steps can be used:<br>

* Import the [[Check_Files_2d_sh_obj |sh_obj]] check file. This file is written sequentially and the last entry is the final object TUFLOW was able to process. The final triangle is shown in red below:<br>

* To remove this in QGIS, the layer needs to be made editable and "cleaned" with the v.cleanFix Geometries tool from Processing Toolbox.

* To remove this in MapInfo, the layer needs to be made editable and "cleaned" as per the images below.<br>

If the above doesn't helpfix the issue:

*Try adjusting the TIN angles. Use <font color="blue"><tt>TIN Angles </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>95,1</tt></font> command in the .tgc file before reading the TIN.
