open TELEMAC-MASCARET The mathematically superior suite of solvers

Sorry for the question:
I want to know which keyword was missing in my first steering file, so when I run it with the keyword it would work.

Not sure, as you might have seen I used a different solver which I used for another river simulation. I'm pretty sure it is with your numerical settings.

How did you end up make your 'first' steering file? You copied from an example?

Please note that by coping a steering file I might have changed some parameter (roughness etc.), but at least you have something to start from.

I made my steering file from the baxter example and a example out of the forum.
For the next simulation I'll use the friciton file I prepared with the software Janet and I'll skip the advection part.

Hello,

I don't want to open another thread at the forum, so I will ask my questions regarding the postprocessing right here (Post-Processor BLUE KENUE):

- I produced a longitudinal section from the inlet to the outlet. Now I just want to extract the values for the velocity and water depth exactly at the points along the line out of the results file. Is there a possibility to extract the velocity/water depth along the line?

- I tried the keyword "STOP IF A STEADY STATE IS REACHED". Now the simulation has a steady state, the fluxes are the same at the inlet and the oulet but the simulation is still running. I set the duration on 1500. Will the simulation stop after the duration is over or after it reaches the steady state?


- While I visualized the result of the simulation, I just want same size fo arrows across the channel, but right now the arrows are as big as the velocity behind it. Is there some way to change that?

Sorry if there is way shown in the manual but I don't find it.

be added to the last question:

when I'm deleting the duration in the sterring file telemac stops the simulation because of reaching the steady state at the first step (0 sec.).

Do I have to add some keywords in the steering file to get the steady state?

Please look attached for my steering file

Hi,
I'm not having experience with stop at steady state, but you start of a previous computations file, so if you have steady state as initial condition, it's logic the simulation stops after 0 sec.

For your BlueKenue questions:

Yes you can get points along a line, using resample to create points a long the line and tools=>maps object to project the variable you like. (I believe this is in the tutorial)

Not sure you can make the arrows a fixed length.

Hope that helps,

Patrick

Thank you for your
Sorry I don't start of a previous computations file. I started from the steerin file you sent me. I changed just the friction data.
While I'm running your steering file, I recognized that I dont get a steady state. The simulation won't stop at a specific point, it will stop after the duration is over.

My problem, why I opened this thread still exists. I want a simulation with a steady discharge (324.0 m3/s) at the inlet and I need to modell the outlet with a rating curve (stage-discharge curve). Everytime when the simulation is running there aren't results in the the results file or telemac eject a lot of different errors.

Your steuer_2019-02-06.cas file still has COMPUTATION CONTINUED = YES, unless you use another file then what you uploaded.

If you do start of with a constant initial elevation and the .liq file, I guess it might be due to the fact that the initial discharge is set at 0.0m3/s. I would try putting it on 10m3/s say. If that doesn't work, I won't be able to help you further....

PS, I'm not understanding why you like to have a stage-discharge curve at the downstream boundary whilst using a steady discharge upstream. A stage-discharge curve would only be useful with time variation discharge.

I used a different steering file, you are right.

I thought a stage-discharge-curve is used in every case. For example at steady state simulation of the baxter tutorial.
When I'm trying to put it on 10 m3/s this error appears:

I can excplain my problem: When I'm running your steering file, the height at the outlet is locked to 307.7m.But I just want to stop the simulation when the height of 307.7m is reached. At this particular height the discharge at the inlet should be the same as the outlet (which should be 324 m3/s at the inlet and -324 m3/s at the outlet)

When I run the simulation with the steering file you gave me, the water depth and the height of the free surface will still increase by time, thus it isn't stationary. I forgot to say I want a stationary simulation. I'm so sorry, that I don't say it before.
