open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello community,
Could any one tell me if there any size limit for the telemac2d output file (selafin file) ?.
I have a very big file (more than 160 GO) for a duration of 40 years with a 1 hour period for the graphic printing. Neither the telheader.m nor BlueKenue give the right number of timesteps (NSTEPS). Even more, the telheader gave to me 18 years as total duration instead 40.
Please see the attached to find out the final iterations ( log file ).
Any idea or kind of help will be appreciated
thank you in advance

Hi Mourad,

we had result files in the order of 230 GB in size and were able to read them in matlab. So it should work. Maybe the limitation is on your own pc?

What we regularly do is split up the computation in different parts. In your case you could run first 10 years and then use computation continued and start the next 10 years and so on. This way you'll have smaller result files.

Another thing you can do if you know your way into the code is to ask output for specific points only in order to reduce the file size of your results. You could combine this with map output with a larger interval (1 day for example)

My experience with blue kenue is that these files are too large to handle in BK.

Hope this helps,

Sven

Thank you sven for the reply,
I do know handle the matlabl functions for telemac output processing, i did it with a fortran routine too but still the number of grafic record (m.NSTEPS) is false... Annother thing goes wrong with telstepr.m : you can run it for imaginary records (greater than the last one) I mean you can do the folowing :

m=telheader(full path of your results.slf)
mm=telstepr(m,m.NSTEPS + n); % wher n is an integer geater than 0

Run of successive simulations is a good idea actually, I think this is the only alternative in my case.

thanks again
