Control Sections - Error 9 years 2 months ago #18215

jstark

Hello,

I'm trying to use the control sections option to compute discharges but I get an error during the initialisation. If I don't use control sections, the simulation runs fine. The output listing tells me the error is in the partel_T2DGEO.log file. This is what that file looks like:

Does anyone know what's wrong and how to solve this?

riadh	Hello It seems that you are using version v6p2. If I'm not wrong, there were bug in the parallel version when dealing with control sections. Try to run you model on a single processor to be sure. If it is the case, please upgrade to last version. with my best regards Riadh ATA

jmhervouet	Hello, The algorithm looks for a path in the mesh, made by segments, starting from the first point of your section, and ending by the second point. The algorithm will fail if there is an obstacle on the way. Are you in that case ? With best regards, Jean-Michel Hervouet

jstark	Dear Jean-Michel and Riadh, Thanks for your replies. I forgot to mention in the first place that I tried serial mode as well and it didnt work either. What exactly do you mean by obstacles? My control sections are crossing the closed boundaries of the mesh at both sides of the estuary/river. Could that be a problem? I attached a screenshot as an example of one of the sections: Jeroen

jmhervouet	Hello, OK, I see that exactly this example could create a problem at the beginning. On the top you seem to start from a point in the mesh and then you cross a region which is outside the domain. Could you try to choose: 1) existing points of the mesh as beginning and end of control sections 2) no exit of the mesh in th estraight line between those points With best regards, Jean-Michel Hervouet

jstark	Thank you for this advice. I moved the start/end points of the sections just inside the model domain and the simulation seems to be running fine now. Best Regards, Jeroen

CUSIPUMA AYUQUE OFFLINE Fresh Boarder Posts: 26	Hi everyone, could you help me , please. I use hotstart for simulation sediment transport with Telemac3D when run, I have a problem with time dependent recording, see this picture. I do not known what happend. Attachments: 123.png (85KB)

Pablo OFFLINE Moderator Posts: 316 Thank you received: 121	Hello, It seems you are messing around with the previous computational file to launch the hotstart simulation. Check if the number of variables is correct and if the previous results are coherent with the follow-up simulation. best wishes, pablo

CUSIPUMA AYUQUE OFFLINE Fresh Boarder Posts: 26	Dear Pablo, It is advisable to use the previous computational file to launch the hotstart simulation, what do you recommed? I want to analize bed evolution and secondary flow en meander river. Many thanks. Magaly C.
