SULEC
SULEC is a finite element code that solves the incompressible Navier-Stokes equations for slow creeping flows. The code is developed by Susan Ellis (GNS Sciences, NZ) and Susanne Buiter (NGU). Its current characteristics are:
- 2D/2.5D/3D
- Thermomechanical
- ALE (Arbitrary Lagrangian Eulerian)
- 4-node linear velocity, constant pressure elements
- 8- and 9-node quadratic velocity, linear pressure elements
- Tracers track materials
- Uzawa pressure iterations
- Powerlaw creep viscosity
- Drucker-Prager type plasticity
- Elasticity
- True free surface with simple implementations of sedimentation and erosion
- Extended Boussinesq
Tests passed:
- Reproduce lithostatic pressure for gravitational body force model without external forces
- Viscous pure shear (test of free surface)
- Viscous Couette flow (tests velocity and pressure)
- Viscous Poiseuille flow (tests velocity and pressure)
- Stokes flow (sinking cylinder)
- Cavity flow
- Viscous relaxation of a sinusoidal perturbation (tests free surface) (see also Crameri et al., GJI 189, 2012)
- Pressure field around a rigid inclusion (Schmid and Podladchikov, GJI, 2003)
- Viscoelastic pure shear
- Viscoelastic simple shear
- Recovery of original shape of deformed elastic block
- Mohr-Coulomb shear zones in compression (see also Lemiale et al, PEPI, 2008; Kaus, Tectonophysics, 2010)
- Steady-state temperature gradient with basal temperature or basal heatflux
- Halfspace cooling
- Couette flow with shear heating
- Latent heat in solidification of a sill
