Usually I call this set "Qonvergence Quartet" (with "Q" as the "q" in Abaqus, which stands for "quality"):

1. *CONTACT (general contact)
2. *STEP, UNSYMM=YES (unsymmetric solver)
3. *STEP, NLGEOM=YES (geometric nonlinearity)
4. *DYNAMIC, APPLICATION=QUASI-STATIC or EXPLICIT (transient dynamic analysis)

Mnemonic: Immanuel Kant (pronounced like "CUND"), German philosopher with the (great, but likely misattributed) quote "There is nothing more practical than a good theory"

Customers have told me that they have a poster-sized printout of this Qonvergence Quartet hanging in their simulation department.
