Respected Nick Papior,

Sir Iam using SIESTA v4.0.2

I want to fix electrode position in scattering region calculation. In manual of v4.0.2 SIESTA it is given as

%block GeometryConstraints

position from -1 to -8 # to fix atoms

%endblock GeometryConstraints

but when i tried this atoms are not fixing there respective positions.

i also tried many syntaxes to fix positions but nothing worked.

Any help will be highly appreciated.

Thanks & Regards

Shanmuk
