The distance between XS is defined in Cross Section Data window Downsteam Reach Lenghts

You can see

It is an App to build very quickly RAS geometry.

you can download a simple App to move the cut lines because the RAS 5.0.3 only move the axis.
In the excel you have to define the X and Y desplacement.
Clicking on RUN button the App will open a shell to select the RAS project and the geometry you want to modify.

Good luck

Thomas, you have to define dot as decimal separator in window setting

Joe,
usually the hot-start is used to continue previous simulation or to create the initial condition when the model is complex or unstable for low discharge using the steady state initial condition.
In the last case you have to run a simulation starting with initial conditions those are stable and decrease the flow up to the discharge you want to use as initial condition for your simulation and than save the hot-start. Obviously the simulation must be stable, if not you have to change something in the geometry.

Joe,
it is not clear to me.
Did you create an hot-start file and the model crash when you use this hot-start or the model crash when you are running the model to create the hot-start?

You can find in Users Manual Chapter 8 pag. 8-22.
It is only for unsteady simulation, for steady simulation you don’t need to fill this table.

In Geometric Editor, on menu Tables click on Reach Lenghts.

What values do you have in this table?

Giacomo,

the pilot flow is in m3/s and you have to define it based on the discharge upstream the inline structure. If pilot flow is larger than US discharge you dry out the US reach.

Hi Jens,

in your completely 2D mesh you don’t have a breakline on embankment so you don’t have cell faces on the top of embankment. I’m not sure that the embankment is well represented. Are you sure in the 2D results there is no flow across the embankment?

Jens,

in my opinion the width of flow between 2D and 1D model happen only on the width of XS -1700 (the first of 1D model) instead in the fully 2D model this width is much larger. Are you sure there is no flow in that part?

In case there is flow you should add a lateral weir to connect 2D with the downstream XSs

I’m sorry, try with this:

Mike,
I wrote a VBA program in Excel, using HECRASCONTROLLER, to export RAS geometry.

You can download it from:

Let me know if it can help.

Katariina,

I have replied to your other post “How to model pumping station without outlet”.
