  Hi,
  I've recently been trying to simulate a radial diffuser with simplified boundary conditions (emulating the compressor). CFX has proven to be incapable of solving the domain so I have since moved to Fluent which has been able to reach a converged solution. I'd like to link Turbogrid with Fluent to streamline a parameterisation process I have planned, but I'm unable to link/connect the two modules (see the image below). Is there any way of doing it, or will I have to export the mesh as a .def file each time I change the geometry?

  Does Fluent Open standalone(separately)?
  If not What is the error?
  Can you verify that you have the latest Grphics card Driver installed?

    I'm working on a remote server which doesn't have a graphics card installed.
    When connected to Turbogrid, Fluent opens, begins to load and crashes shortly afterwards, displaying an error message (shown in the previous post, and printed below). I can manually set up a simulation in Fluent using a .def file exported from Turbogrid, but connecting the two blocks doesn't work.
    In case you couldn't see the error message due to it being an image, here it is, printed below:
