[gpaw-users] LCAO overlap issue

[Glen Jenness]

Dear users,
I am trying to optimize a geometry of a zeolite using LCAO mode, but I keep
getting:

    self.calculate_expansions()
  File
"/opt/shared/gpaw/0.9.0.8965/lib/python2.7/site-packages/gpaw/lcao/overlap.py",
line 749, in calculate_expansions
GPAW CLEANUP (node 6): <type 'exceptions.IndexError'> occurred.  Calling
MPI_Abort!
    l_Ij, phit_Ijq)
  File
"/opt/shared/gpaw/0.9.0.8965/lib/python2.7/site-packages/gpaw/lcao/overlap.py",
line 525, in calculate_expansions
    tsoe = calc.calculate_expansions(l1_j, f1_jq, l2_j, f2_jq)
  File
"/opt/shared/gpaw/0.9.0.8965/lib/python2.7/site-packages/gpaw/lcao/overlap.py",

    oe = self.transformer.calculate_overlap_expansion(a_q, la, lb)

    a_g = (8 * fbt(l, a_q * k1**(-2 - lmax - l), self.k_q, R) /
  File
"/opt/shared/gpaw/0.9.0.8965/lib/python2.7/site-packages/gpaw/lcao/overlap.py",
line 99, in fbt
    ifft(C[l][n] * f * r**(1 + l - n), 2 * m)[:m].real)
IndexError: list index out of range
GPAW CLEANUP (node 4): <type 'exceptions.IndexError'> occurred.  Calling
MPI_Abort!

Any ideas what can cause such an error?

Thanks!
Glen
