Dear Roberto Guerra,
"Optical: Number of bands = 26"
--> are you running the Si example? The example has 2 Si atom
with DZP basis set. If you use DZP basis set, the maximum number of
possible band for the example is 26, since each of Si atom could
produce 13 bands under DZP basis.
if you want to increase the number of states, set basis set to TZDP
or something else(see manual).
NumberOfEigenStates and Optical.NumberOfBands must be less than
the maximum possible number.
MeshCutoff has nothing to do with this.
Best Wishes
