How to modify an existing unsteady flow model

[eddythefish74]

Hi !¨

I am having trooble modifying an existing HEC-RAS unsteady flow model.
Basicaly I just want to add new cross sections and modify some other.

I started by adding cross sections but when I run the calculations, the model calculate the water levels for every other sections but not for the one I added.

I check and none off the added cross section are link to the boundaries conditions set by the previous user.

Anyone knows how to add these modifications in an existing model ???

Thanks !!

Cheers

Perhaps the geometric pre-processor needs to be run to incorporate your changes.
