I’m utilizing fGMRES and require guidance on how to implement the restart number.
-ksp_gmres_restart XYZ?
Would you kindly provide me with examples relevant to my case, such as the Navier-Stokes or Stokes equations using “-ksp_gmres_restart”? Additionally, I’m currently working with splitting the solution of the linear system into three variables (u, ksi, p) in order to calculate erroru, errorksi, and errorp. I need to use the fieldsplit preconditioner to split the linear system. If possible, please provide examples if you have it to support my case. Thank you.
