used two-level initialization and intra-comm:sockets Incompatibility issues

1

Hi!
I am studying the partitioned-pipe case in the tutorials. I set the intra-participant communication to : <intra-comm:sockets port=“0” network=“lo” exchange-directory=“.”/>, and I used two-level initialization: use-two-level-initialization=“true”. I found that there would be errors as shown in the picture, but when I used <intra-comm:mpi exchange-directory=“.”/>, there would be no errors. The preCICE version I installed is 3.0.0. How can I solve this problem?

Thanks so much!

Hi @lzx,

as the error message states, you need to look at the other participant for more useful information. What does the other participant report?

Hi! the other participant report some information about openfoam and segmentation fault in these photos:

I have set openfoam run in parallel mode,and I test flow-over-heated-plate case in the tutorials,the same problem occured.

@lzx the error message is still not visible in this image: I only see that the issue occurs in the initialization. Screenshots will not help, please upload two text files with the complete output of both solvers.

You can do this, for example, with:

mysolver | tee mysolver.log 2>&1

(the 2>&1 is important, to redirect the errors into the same log file)

The fluid1.log and fluid2.log files are all errors information,and I offer Fluid1_rank0.log and Fluid2_rank0.log files which are the information of rank 0 in two participants,I hope that can be helpful.
