I am having issues getting Nektar++ to recognize ARPACK. When I run through the channel-flow tutorial, in the Channel-Coupled.xml section, I get to the following command:

IncNavierStokesSolver Channel-Coupled.xml

Then, I receive the following error:

Value ‘Arpack’ is not valid for property ‘DRIVER’

I’m very confused how to link Arpack (which is going to be installed to my personal directory rather than on the main section of the cluster, because I do not have permission to install Arpack globally). It is installed at $HOME/ARPACK/

In ccmake .., I point the ARPACK_LIBRARY flag to $HOME/ARPACK/libarpack_LINUX.a, and then I changed the NEKTAR_USE_ARPACK flag to on.

Is there something I am missing???
