hi 2 all,<br><br> I have one question. In epsilon.x, the k points is not automatic option. Sir, means how to give the K points option i.e. we have to give only irreducible k points or like for the calculation ='bands' , we have give the path (like G{0,0,0}-->X(0.5,0,0)). If we have to give the irreducible points , how to calculate those points ???? can i do this , that run the pw.x with a mesh like 4*4*4 grid and the number of k points in the scf output are the required k points<br>
like in a scf out <br> number of k points= 8<br> cart. coord. in units 2pi/a_0<br> k( 1) = ( 0.0000000 0.0000000 0.0000000), wk = 0.0312500<br> k( 2) = ( 0.0000000 0.0000000 0.2829528), wk = 0.0625000<br>
k( 3) = ( 0.0000000 0.0000000 -0.5659056), wk = 0.0312500<br> k( 4) = ( 0.0000000 0.2500000 0.0000000), wk = 0.0625000<br> k( 5) = ( 0.0000000 0.2500000 0.2829528), wk = 0.0625000<br>
k( 6) = ( 0.0000000 0.2500000 -0.5659056), wk = 0.0625000<br> k( 7) = ( 0.0000000 -0.5000000 0.0000000), wk = 0.0312500<br> k( 8) = ( 0.0000000 -0.5000000 0.2829528), wk = 0.0625000<br>
<br>, means i have 2 give these k points with their weight set to equal to each other. And in out of these i have to choose also because like 0 0 0.282 and 0 0 -0.282 will yield the same results ?? M i right ??? Please advice ???? <br>
