Many thanks, that has helped! 

What factors influence the proportion of time taken to solve the linear equations (i.e. under what circumstances would the LE wall clock time be >80%)? I have been trying several things today and I am struggling to see the relationships. Most things I am doing does seem to change the time to solve the linear equations, but equally this changes the time to compile the LEs so the percentage stays approximately the same, or if it does change it is never >80%. (trying different meshes, different turbulence models, different boundary conditions etc.)
