WebSep 23, 2016 · At CO’s peak, marked by the black cursor, O 2 rises. The blue trace would indicate a bad catalytic converter. Its oxygen level rose from .2 percent to 2.1 percent. That equates to a 1.9 percent increase, which is above our 1.2 percent standard and indicates a bad converter. The green trace comes in at .9 percent O 2. WebNov 19, 2024 · SET UP CALCULATIONS: Create a folder with the desired POSCAR unit cell. Decide on the size of supercell to do calculation on. For example, 2 x 2 x 2. Generally we aim for a supercell that has similar a, b, and c lattice vector lengths. In command line, enter: phonopy -d --dim="2 2 2".
