Dear all,
Which visualization software will describe the fermi surface like the one given in paper below. For a magnetic calculations with hubbard U (LDA+U or GGA+U) , how higher the k-points in general need to be taken so that one can be able to show the fermi surface. I followed the python script available to convert the vasp outputs to bxsf format and can show the fermi surface using xcrysden. 3D fermi surfaces given in the link below are excellently shown. Which software can show the fermi surface that way? Can anyone suggest me regarding how this can be achieved?
Thank you

I followed the link and found this figure, which I could produce in Maple or Tecplot if I knew the equation or had a data set.
Hi Anuroopa,
You can just import your VASP calculation folder in the CINEMAS application(https://ikst.res.in/cinemas) being developed by us.
And without the need for any scripting to post-process VASP output, 3D fermi-surface can be visualized through an easy-to-use GUI.

This is the link to a video tutorial on how CINEMAS throught its easy-to-use GUI can visualize 3D Fermi-surface from VASP output files, without any program scripting.
