When a mesh is generated, a mesh log is also created.
00:08
This log contains information on any errors or warnings.
00:12
Some examples of these warnings include:
00:16
Element contains more than 100 triangles:
00:20
This means that your object geometry is not optimized and ICM had to create many small triangles
00:28
and aggregate them into an element.
00:31
Ideally, these should be investigated and resolved.
00:35
This is usually a simple process of adjusting some object vertices, because they are very close but not snapped together.
00:44
Manholes are inside the same element:
00:48
This warning is usually acceptable, but having two nodes linked to a single element may increase the chance of flow limiting occurring.
00:58
If needed, you could either move one of the nodes into an adjacent element, or use a break line to enforce two separate elements.
01:08
Element aggregated across boundary:
01:12
This warning is usually acceptable and provided for information.
01:18
The meshing algorithm has found a small triangle outside of a polygon boundary,
01:24
but aggregated it into an element containing triangles from within the polygon.
01:30
So, the properties of the triangles may have differed.
01:34
This is done to try to avoid small elements.
01:38
Unable to calculate internal point:
01:42
This is an object geometry error, usually caused by void objects.
01:48
These should be investigated and resolved by adjusting the inconsistent objects.
01:54
The key thing to look for is any elements which are less than ½ the minimum element area.
02:02
These will be listed in the log and should be inspected and corrected where possible
02:08
as they could be detrimental to the simulation speed.
02:12
Pay attention to the mesh log as you are generating meshes,
02:16
as it can help you make corrections and adjustments to your 2D mesh objects.
