Hi all,

I’m new to channelflow and I am using it for my Master’s Thesis.

I’ve been trying to install channelflow and have been encountering some difficulties as I can’t get all the subroutines to pass when make test is invoked.

I tried it both with -DUSE\_MPI=off and -DUSE\_MPI=on and both has around 93%~ test passes

I have attached the log below to avoid clutter.

The common failed subroutines are:

1. time\_integration
2. io  
3.vector2field

Thank you!

You could try running the tests manually and seeing what happens. There should be binaries for them in /build/tests/test\* They tend to be pretty verbose.

It is a bit weird for the io test to fail - perhaps something fishy is going on when the tests are run.

Cool. I’ve found the error. I think there’s some overlapping of the package HDF5. I’ve installed HDF5 from the source code. I’ve also installed anaconda (a platform for python) which has also HDF5 itself.

I saw that HDF5 is required for legacy file formatting. I am thinking of disabling HDF5 actually I am not sure what do legacy file formats refer to. I’ll probably use matlab/paraview for post-processing which I saw that NetCDF supports. If thats that case I probably don’t need HDF5?

Warning! _ **HDF5 library version mismatched error** _  
The HDF5 header files used to compile this application do not match  
the version used by the HDF5 library to which this application is linked.  
Data corruption or segmentation faults may occur if the application continues.  
This can happen when an application was compiled by one version of HDF5 but  
linked with a different version of static or shared HDF5 library.  
You should recompile the application or check your shared library related  
settings such as ‘LD\_LIBRARY\_PATH’.  
You can, at your own risk, disable this warning by setting the environment  
variable ‘HDF5\_DISABLE\_VERSION\_CHECK’ to a value of ‘1’.  
Setting it to 2 or higher will suppress the warning messages totally.  
Headers are 1.10.0, library is 1.10.4

edit: I used matlab to read NC files which worked

Hi Chihin,

good that you solved your issue.  
Just a comment on the legacy format HDF. If you are new to Channelflow and directly start with version 2.0, you can happily disable HDF and only use NetCDF which is more performant.

HDF was the main format for Channelflow 1.5. Users that worked with that older version might want to read existing HDF-data.

Best,  
Florian

Got it, thank you Florian!
