ERROR 10143 - Number of requested nodestrings is greater than upper limit (<max_nodestrings>).

Description

The total number of nodestrings in the mesh exceeds the internal limit of 500. This is the combined number of nodestrings specified in the .2dm mesh file and via 2d_ns GIS layers.

Suggestions

Where possible, reduce the number of nodestrings in the mesh by simplifying or splitting the nodestring GIS data, or by removing nodestrings that are not needed for the current simulation. If the number of nodestrings cannot be reduced, contact support@tuflow.com to discuss options for increasing the internal limit.
