FBIAS_A
FBIAS_A = [real (array)]
Description: The flag FBIAS_A defines the size of step (Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://www.vasp.at/wiki/restbase/vasp.at/v1/":): {\displaystyle A_{\mu}} ) for the Fermi-like step-shaped bias potential of the following form:

The number of items defined via FBIAS_A must be equal to Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://www.vasp.at/wiki/restbase/vasp.at/v1/":): {\displaystyle M_4}
, otherwise the calculation terminates with an error message.
