open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi Riadh,

I tried it and it is now working on a singel core, but not in parallel. But due to the big mesh, single core is no solution...
I also changed MAXFRO in line 196 of front2.f to 5000, but got still the old error message with the 3000 in parallel.
But I hope you have now a new idea...

Thanks,
Gabi

Hi Gabi,

since we discussed yesterday about it and I had the same problem some time ago:
The problem may come from the mesh partitioning step.
Have a look into partel ...\sources\utils\partel:

partel.F(163): INTEGER, PARAMETER :: MAXFRO = 3000
partel_para.F(146): INTEGER, PARAMETER :: MAXFRO = 3000

So it would be nice if the keyword MAXIMUM NUMBER OF BOUNDARIES applies also to partel.

Hope this helps,
Clemens

Hi Clemens,

thank you very much. I was looking for your old post, but didn't found it..

Many, many thanks,
Gabi

Hi all,

I just found out that the MAXFRO Problem still exists in V7p1r1 in parallel.

Maybe somebody in the telemac Team can put on the list for the next release?

Many thanks,
Gabi

Hello Gabi,

Could you explain what is exactly the MAXFRO problem? MAXFRO is now a keyword and can be as large as wanted (see What's new in home page), it triggers dynamic allocations, but the default value has been reduced to avoid unnecessary memory allocation in most cases. In view of this is there another problem that I missed?

With best regards,

Hello again,

Hum, yes, you are right, it remains in the domain decomposition part... sorry I forgot that.

Hi all,

I have the same problem with version V7.2.

Alghouth, I have write the words :"MAXIMUM NUMBER OF BOUNDARIES = 1000" in cas file but not effect.

Please help me figure out the problem.

Thanks inadvance.

Hi,

like Konsonaut wrote same time ago, you have to change

partel.F(163): INTEGER, PARAMETER :: MAXFRO = 3000
partel_para.F(146): INTEGER, PARAMETER :: MAXFRO = 3000

in partel ...\sources\utils\partel

Regards,
Gabi

Thanks Gabi,

I run okie after I upgraded version v7p3.

Anyway thanks.

Cheers.

Have you succeed just changing
partel.F(163): INTEGER, PARAMETER :: MAXFRO = 3000
partel_para.F(146): INTEGER, PARAMETER :: MAXFRO = 3000


Because I tried but it doesn't change anything.

Have you juste change these parameters or have you recompile something ..; ?
Thanks in advance,

Laurie
