      This can be witnessed when a distributed calculation is being run, using the AVX2 interconnect option (“-platform=intel”) For the HDF addon to be properly loaded, the FLUENT_ARCH environment variable has to be set to lnamd64 on all nodes, which may not be the case depending on your simulation environment To work around the issue you need to manually define the FLUENT_ARCH environment variable, by adding -mpiopt=”-e FLUENT_ARCH=lnamd64″ to your startup command.
