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:

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
