open TELEMAC-MASCARET The mathematically superior suite of solvers

hello Andreas,

I didn't have any problem with your mesh and the calculation is made without any sigsegv on my computer with different compilers. Do you use the version of the trunk or another one ?

In general you can check your mesh by adding CHECKING THE MESH=YES
In your case it says that you have 55 over constrained triangles which means that they are not taken into account

I would just add some comments about your calculation your time step is far too big, for your mesh a time step of 10 would be better.

you ask for option 1 of breaking dissipation but give the parameters of option 2, they will be ignored and default parameters of option 1 will be taken into account

hope it helps

T.

Thank you for your assistance.I took into consideration all your comments and the simulation is executed.However when I set the related keywords to take into account the diffraction phenomenon,I get another segmentation fault.Do you think this is memory related?

Kind Regards,
Andreas

I tried your case with diffraction and I got some messages like this
**** OUPS 10303 9

It means that node 10303 has 9 elements as neighbour and for a reason i still don't know Diffraction is allowed for up to 8 neighbours, i will try to see if it is just allocation or if there is something more behind.

Anyway be careful diffration in tomawac is not very precise in some case.

I will do something cleaner soon but meanwhile you can add this routine to your fortran user the limit is 10 instead of 8.

Thank you Thierry I will add the subroutine in the fortran file and let you know about the results

When trying to use the aforementioned subroutine I get the following errors,is there something I can o to fix it?

Hello
It seems you do not use the last version of telemac. In V7P2, ILM_POIN,CLM,KACC,NB_C,SUR_P are presents in declarations_tomawac.

Hi
is "CHECKING THE MESH=YES" a command of .cas file?
thanks

hello
yes exactly you can put the command in your cas file .

THANK YOU
