Problems sampling UPrime2Mean
 

Hello everyone,

I'm trying to sample data from the channel395 tutorial with the sample utility, but I get the following error when doing so:

#0 Foam::error::printStack(Foam::Ostream&) in "/model/giampani/
OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so"

Segmentation fault

When I use it for U, UMean etc, everything works fine, so I think there is no problem with the probe line (I've already tried all types...). Furthermore, when trying to sample UPrime2Mean.component() or mag(UPrime2Mean), no error message is given, but no files are created as well. When sampling other cases where UPrime2Mean is present, the same problem arises...

Any ideas?

Thank you!

Maybe you can try to calculate the components of UPrime2Mean first with
and than do the sampling?

Hi Sebastian!

Thank you very much! It seems to work perfectly!
By the way, do you know why I couldn't sample the variable directly? Would it be a bug?

Regards,

Leonardo

Well, I am not sure. I am using version 1.5.x and can calculate the field directly.

I want ask what is UPrime2mean, the computational formula of it and transient k is the same, but do they the same in real physical meanings? Would you please tell me?

Why do I think, that you didn't use the forum search functionality or have a look at the code to find an answer yourself? Please correct me if I am wrong :)
