File format "MED" not available

[Veribum]

Hi everybody, I have problems with my first simulation in CS.
I set up all parameters but simulation can't start and in the preprocessor.log this message appears:

.------------------------------.

code_saturne version 7.0.4-patch (built Wed Aug 10 16:38:23 2022)

There is a problem with MED package installation, I thought. So I tried to re-install it manually but another issue occurs:

I tried to launch the command:
./configure --with-hdf5bin=path of the bin directory
but it doesn't work.
How can I fix this issues?

Thanks.

Hello,

I recommend trying the newer MED 4.1 instead of MED 4.0 (to reduce the risk of compatibility issues with meshes generated by the latest SALOME versions).

When building MED, i usually provide the whole HDF5 path, using '--with-hdf5' rather than just hdf5bin,

But if you a running on a Debian-basd system, you may simply be missing the hdf5-tools package (I'm not sure how the packages are split or named in Red-Hat or SUSE type distributions). Can you try installing that ?

Also, be careful if you have a very recent (or rolling) distribution using HDF5 1.12. MED requires HDF5 1.10, so in this case, you would need to install an older version also.

Best regards,

Yvan

Hi,

I am facing the same issue.
I have installed code_saturne-7.0.5. , I thought it was specific to my case, but today I ran one of the examples and I still get the following error.

"File format "MED" support not available in this" (even after assuring that it has MED compatibility in version specifications)

I have attached the image of the error and the details of my code_saturne specifics.

Please let me know your suggestions when time permits.

Thankyou!

Hello,

In the 2nd image, I do not see the 1st 3 lines, containing the install paths, but I see the build dates are not exactly the same (3 minutes difference) in the 2 cases, so I suspect that either :
- You have 2 different installs, one with MED support, the other without.
- You overwrote the fixed install with MED support with an older setting without MED support.
I'll let you check which might be the case..

Best regards,

Yvan

Hi Yvan,

Thanks a lot for looking into the details — you were absolutely right! I've now corrected the environment to point to the right installation, and everything is working fine.
Really appreciate your help!

Best regards,
