  I get this error when trying to run an FSI simulation in the tutorial pack .
  /petastore/ganymede/home/SoftWare/List-Of-Software/Ansys-2022R2/v222/fluent/fluent22.2.0/lnamd64/3ddp_node/fluent_mpi.22.2.0: error while loading shared libraries: libansysfluidshdfsdk.so: cannot open shared object file: No such file or directory
  
  This happens when I load Fluent. What causes this and could you advice on a fix?

  Check if environment variable I_MPI_ROOT is set, if so unset it and try again.

  Here is what I found in a launched Fluent v222 console:
  >!ldd /apps/ansys_inc/v222/fluent/fluent22.2.0/lnamd64/3ddp_node/fluent_mpi.22.2.0 | grep libansysfluidshdfsdk.so
  libansysfluidshdfsdk.so => /apps/ansys_inc/v222/fluent/lib/lnamd64/libansysfluidshdfsdk.so (0x00007fe31c951000)
  make sure /petastore/ganymede/home/SoftWare/List-Of-Software/Ansys-2022R2/v222/fluent/lib/lnamd64/libansysfluidshdfsdk.so exists, if not check /petastore/ganymede/home/SoftWare/List-Of-Software/Ansys-2022R2/install.log and install.err, restall.
  Run below, copy and paste output messages:
  /petastore/ganymede/home/SoftWare/List-Of-Software/Ansys-2022R2/v222/fluent/bin/fluent -env
  Also try:
  /petastore/ganymede/home/SoftWare/List-Of-Software/Ansys-2022R2/v222/fluent/bin/fluent 3d -t2 -g
