Hi Isaac, Have you also built Nektar++ with Hdf5 by activating the option NEKTAR_USE HDF5 ? Many thanks, Alexandra On Mon, 23 Sept 2024, 11:42 Isaac Rosin, <isaac.rosin1@ucalgary.ca> wrote:

Hello Nektar++ users,
I just installed Fedora 36 on my computer. I chose this distribution specifically because Nektar++ supports it.
I made sure to install all of the required packages for each utility and solver I needed before installing libnektar++, libnektar++-openmpi and libnektar++-mpich. Then I installed the libnektar++ packages, nekmesh, fieldconvert serial and mpi versions and the incnavierstokes-solver and tried to run the command `NekMesh geometry.msh geometry.nekg` and got the following message: ``` Fatal : Level 0 assertion violation No such module: HDF5
Available classes: Xml: IO with Xml geometry XmlCompressed: IO with Xml geometry
terminate called after throwing an instance of 'Nektar::ErrorUtil::NekError' what(): Level 0 assertion violation No such module: HDF5
Available classes: Xml: IO with Xml geometry XmlCompressed: IO with Xml geometry
Aborted (core dumped) ```
I know that my files are not the issue because I have been able to execute this command with my past installations of Nektar++. I got the same error when I tried FieldConvert too using a version of the .nekg mesh I had already created on a previous installation. It seems like NekMesh does not see my HDF5 installations. How may I resolve this?
