HEC-RAS 2D Analysis Error – Weir Stationing Not Increasing
When performing a 2D HEC-RAS analysis that contains storage areas and 2D connections, the HEC-RAS program might report the following error message.
When this error message is reported, it might not be obvious what is wrong with the model or how to correct it. The below example illustrates this problem and how to correct it.
Revising the mesh so that the mesh boundary is adjacent to the storage area/2D connection will correct the problem and remove the error message.
The below image shows a close-up of the revised mesh boundary and the adjacent connection element.
