hi,
I set "FRICTION DATA=YES" in my t2d steering file and it works well.
But an error occured when coupling with sisyphe.BED ROUGHNESS PREDICTION is set to NO in the sisyphe steering file.
The error message is 'NO FRICTION ZONE DEFINED FOR THE NODE : '.And the error comes from SUBROUTINE FRICTION_INIT（line 120）.
The version is v7p0r1.

Thank you in advance for the help,

HJW

Hello,

If you could post your case with coupling we could have a look at it. Normally the friction velocity is transmitted to Sisyphe, and there should be no interference with zonation because once we have the friction velocity, zones are not used, this is strange.

Hello,

I tested it on single-processor and it ran well.But the above error occured on multi-processor.

Thank you in advance,

Hello,

The whole case would be useful, so that we can reproduce the error. Normally the zones file is splitted so that every processor gets the information for its points. Please note that I cannot run your case in the next 12 days, maybe another colleague will be able to have a look at it.

With best regards,
