open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello all.
I am trying to run a telemac2d v6p1 simulation using a mesh with 320 small islands (about 54.000 elements and 28.000 nodes), but I get the following error:

---

## Error : System command failed for d:\hse_study_project2\inline.MAT\cas5728_tmp\telemac2d.bat :65280

---

What could be the problem?

Here's the full listing

Hi

The default value of the maximum number of boundaries is 300.
In your case, the number of island is larger than this default value.

In décalrations_telemac2d.f, you should change the value of MAXFRO. you could replace 300 by 500 for example.

Warning, you should make a full compilation of telemac after this change!!!
Without this full compilation, you could have eratic computational crashes which will be impossible to debug

Hope this helps

Hello again and thanks a lot for your quick response.
I followed your suggestion and the error seems to be gone. However, the results file contains the following error:
"SEVERE: exception.IOException"
What can I do?
Thanks.
Roberto.

Hello Christophe.
I followed your suggestion from last week (edit MAXFRO and fully re-compile) but the results file seems to have an error (I get the message "SEVERE: exception.IOException" when opening it with FUDAA).
If it is not too much trouble, I have attached the simulation files (.mat) so you can have a look.
Thanks a lot for your valuable advise.
Roberto

Hi
On my computer, it works but the steering file is not well configured.
Avoid printed variables in the listing file.
If you use FV scheme, you should reduce drasticaly the time step. try to use variable time step with a Disired Courant Number...

It works also well with the FE scheme with this steering file for example


I have this partial result


You should give a larger simulation duration to reach a steady state ...

Hope this helps

Hello Christophe.
Sorry to bother you again. The model seems to be running after I tried everything you suggested; however, even though I configured the cas file to print the Froude number during the run, nothing is being displayed (is the model really running?).
I attached a screenshot of the simulation window.
Best regards and thanks again.
Roberto

Hi

It seems that your simulation is not running well or at least we can not conclude if it is really running.
Hereafter some suggestions:

1-Add these key words to your steering file:
VARIABLES FOR GRAPHIC PRINTOUTS = 'U,V,H,F'
GRAPHIC PRINTOUT PERIOD = 10 (change here)
LISTING PRINTOUT PERIOD = 500 (change here)

2-you are using finite volumes kernel, so add these key words to your steering file
EQUATIONS = 'SAINT-VENANT VF'
FINITE VOLUME SCHEME = 1
VARIABLE TIME-STEP = YES
DESIRED COURANT NUMBER = 0.8
DURATION = 200. (change here)

3- There is no need for the following :

STEERING FILE ='cas'
STOP CRITERIA =1.E-3;1.E-3;1.E-3
WATER DENSITY =1000

4- If you want to use finite element kernel, you can start with any validation test case of Telemac and readapt it to your application.

I hope that this helps.
Kindly
Riadh

Hello
I tried all suggestions on all my models and most of them seem to be working now. There´s still, however, one mesh that does not work. This model has the exact same configuration as all others, the only difference is that is has more nodes (about 80.000). I´m attaching the simulation files for this model in case someone can have a look.
Thanks.
Roberto

Hi

You do not indicate how the simulation stops, just at the beginning or later?
could you send us the output listing.

Riadh

Hello Riadh
Thanks a lot for your assistance.
The listing is below.
When I run the same model with the finite element method (instead of FV), it seems to work fine
