[Wannier] Segmentation error in calculating the Fermi Surface

[Payal Wadhwa]

Dear Wannier experts,

I was trying to calculate the Fermi surface of a system having 2 atoms in
the unit cell with a KMESH of 22*22*22. But, when i run wannier90.x, it
gives me a segmentation fault. It works well with 20*20*20.
As it is probably a memory issue, but we can run wannier90 only on one
core. Then how can we use higher k-mesh for these systems?

Can somebody please help me out?

I would be very thankful to you.
