is observed. This sign is confusing, and has been forbidden.

Hello hameed1987,

As indicated in the warning message, the tab character is found in AT LEAST one place in your input file.

The input reader for Abinit does not understand tabs. Therefore, they should be removed from your file. In this case, I found 8 tab characters!

The fixed lines should be (lines 54 to 57):

Code: Select all

 0.6667 0.3333 0.877
 0.3333 0.6667 0.377
 0.6667 0.3333 0.5
 0.3333 0.6667 0

Additionally, it might be wise to add additional decimal places to your input file. While not needed for exact fractions, the decimal representations of 1/3 and 2/3 should be extended.

Best of luck!
