Dear Siesta users,

I am using siesta-trunk-515 and in that I tried a test run for *Fe using U
parameter*.

While running, it is giving an error *"not enough shells"* though the same
input file* without U parameter runs well*. Can somebody please let me know
the possible mistake I may have done?

Any help in the context will be appreciated. Thanks in advance.

Here is the output file with an error.

initatom: Reading input for the pseudopotentials and atomic orbitals
----------
Species number:   1 Atomic number:   26 Label: Fe

Ground state valence configuration:   4s02  3d06
Reading pseudopotential information in formatted form from Fe.psf

Pseudopotential generated from a relativistic atomic calculation
There are spin-orbit pseudopotentials available
Spin-orbit interaction is not included in this calculation

Valence configuration for pseudopotential generation:
4s( 2.00) rc: 2.00
4p( 0.00) rc: 2.00
3d( 6.00) rc: 2.00
4f( 0.00) rc: 2.00
For Fe, standard SIESTA heuristics set lmxkb to 3
 (one more than the basis l, including polarization orbitals).
Use PS.lmax or PS.KBprojectors blocks to override.
