RSQSim Paramter Sweep List
Default Parameters:
• A_1 = 0.01
• fA = 0.1
• B_1 = 0.015
• Dc_1 = 1.0e-05
• mu0_1 = 0.6
• tau0_1 = 60
• sigma0_1 = 100
• ddotEQ_1 = 1
• stressOvershootFactor = 0.1
Optional Slip Weakening Parameters:
• muAmp = 0.2
• muInvDist = 2.0
Physical Parameters (w/range of values):
1. Rate constitutive parameter (A_1)* ~0.01 – 0.006
2. State constitutive parameter (B_1)* ~0.008 – 0.0015
3. Initial shear stress (tau0_1) ~60MPa – 120MPa
4. Initial normal stresses (sigma0_1) ~100MPa – 200MPa
5. Coefficient of friction (mu0_1) ~0.5 – 0.7
6. Critical slip distance (Dc_1) ~1e-4 – 1e-5
Simulation Parameters (w/range of values):
1. Rupture slip speed (ddtotEQ) ~1 m/s – 2 m/s
2. Stress Overshoot Factor ~0.1 – 0.3
3. A-reduction Factor (fA) ~0.1 – 0.3
∗Stress drop scales as (b-a)x σ, so holding (b-a)x σ=0.5MPa while changing a or b is best. We could then only vary one parameter (a or b).
