INIMIX

INIMIX = 0 | 1 | 2
Default: INIMIX = 1 

Description: INIMIX determines the functional form of the initial mixing matrix in the Broyden scheme (IMIX=4).

---

The initial mixing matrix might influence the convergence speed for complex situations (especially surfaces and magnetic systems), nevertheless INIMIX must not be changed from the default setting: anything which can be done with INIMIX can also be done with AMIX and BMIX, and changing AMIX and BMIX is definitely preferable.

Possible choices for INIMIX are:

• INIMIX=0

Linear mixing according to the setting of AMIX

• INIMIX=1

Kerker mixing according to the settings of AMIX and BMIX

• INIMIX=2

No mixing (equal to INIMIX=0 and AMIX=1, not recommended)
