Hello,

OK, I am just back from a conference and could not look for the problem. Strange that it occurred so late in the computation.

With best regards,

Hello Jean-Michel Hervouet,

It's good to have back. I said I found the reason (uninitialized variable in the subroutine) for my problem and it was not true. Actually I accidentally turned off the keyword BED LOAD in SISYPHE so the error started from the beginning but it was not the error I have after 375192 steps.

Now I'm running the model in the debugging mode and it indeed can indicate which line goes wrong in the code. I simply wait until the error occurs again and I will keep you updated.

Have a good weekend,
Qilong

Hello,

After about two days, I finally got the errors in the debugging mode and it indicates that
out_t3d_WesternSc  00007FF70895F901  OV                 181  ov.f
out_t3d_WesternSc  00007FF709B9EA88  MVSEG              116  mvseg.f
out_t3d_WesternSc  00007FF70923F9BF  MATVCT             601  matvct.f
out_t3d_WesternSc  00007FF708A2BB61  MATVEC             286  matvec.f
out_t3d_WesternSc  00007FF708A92F44  DIRI01              95  diri01.f
out_t3d_WesternSc  00007FF70828F14B  DIFF3D             660  diff3d.f
out_t3d_WesternSc  00007FF7080C62FA  CVDF3D             561  cvdf3d.f
out_t3d_WesternSc  00007FF707F101D1  TELEMAC3D         1730  t3dfort.f
out_t3d_WesternSc  00007FF709DF285E  MAIN__             189  homere_telemac3d.f

It is consistent with the previous screen printouts which says it has problem in CVDF3D when dealing with W (vertical velocity). But I still don't know what the reason is behind this error...

Kind regards,
Qilong

Sorry, it may not be the problem in CVDF3D but in DIFFUSION AND PROPAGATION STEP BY WAVE_EQUATION. Because the error starts at line 1730 in telemac3d.f.

Hello,

Well, line 1730 in telemac3d is a continuation line in the call to cvdf3d for velocity W, line where there is CALCFLU(3) ? If this is confirmed, it would be an argument which is corrupted somewhere ?
Actually I thought you had solved the problem, so is it something else ?

Hello Jean-Michel,

I think I made a mistake this afternoon. I checked the code and in my case line 1730 is indeed the place where the CVDF3D (APPEL DE CVDF3D POUR W) is called in TELEMAC3D.

In the original telemac3d.f, the line number is 1705 but I use the modified file you provided with me (the crash problem of k-epsilon model is fixed in the modified telemac3d.f).So I didn't solve the problem and it still happens in my model when it couples with SISYPHE.

This error occurs in the sequence of OV --> MVSEG --> MATVCT --> MATVEC --> DIRI01 --> DIFF3D --> CVDF3D --> TELEMAC3D.

But it's strange that in ov.f, the error occurs at line 181 which is
CASE('YZ    ')
!
        DO I=1,NPOIN
          X(I) = Y(I) * Z(I)
        ENDDO

Does it mean either matrix Y or Z is invalid? I traced back those two variables and I found

Y is MTRA2
Z is T3_03

And in DIRI01, T3_03 is also FBOR which means DIRICHLET BOUNDARY CONDITIONS. But I checked the MODULE DECLARATIONS_TELEMAC3D and found MTRA2 is just a WORKING MATRICES.

Kind regards,
Qilong

Hello,

So I can only look myself at the case, if you send me the files (of the simplest case crashing) to my personnal address, directly or through some DropBox or WeTransfer system.

Thanks Jean-Michel!
I've sent my model to your personal address.

Kind regards,
