CFD BCs in exported .neu file cannot be found by other program

Coreform Cubit Importing/Exporting

I am using HOPR to process the exported mesh .neu file to HDF5 format for later computing. However, the HOPR program could only read the 1st Boundary Condition that I have defined and could not find others (I first made side sets with names such as bcinlet, bcoutlet, bcwall and applied CFD BCs on the side sets). I later checked the .neu files and I saw that the BCs are assigned the same ID?

BOUNDARY CONDITIONS 2.4.6

                     bcinlet         1       272         0         6

 11968    4    1

 11964    4    1

And at the end of the .neu file, cfd bc are listed with identical parameters, and I don’t know if and how are the CFD BCs mapped onto the side sets? Should they be like this? Could you kindly tell me what the four numbers after BCs name are? Maybe I can modify and assign IDs to them manually.

Thank you!

Hi @Feng,

Welcome to the forum. It would be helpful to have a journal file that replicates your problem. Cubit creates a history*.jou file in your default directory that can be used to capture the steps to recreate the problem.

Which exporter are you using?

Thanks,
Karl
