PyFrac version 1.1.1

Version 1.1.1 (November 2020)

• Numerics:
  • New front reconstruction scheme such that the reconstructed fracture front is continuous between cells
  • Non-linear solver now using Anderson acceleration
  • Block Toeplitz elasticity matrix (for isotropic elasticity only)
  • Improved tip asymptotics (notably for leak-off regimes)
  • Improved closure/contact algorithm
• Mesh & Re-meshing:
  • possibility of having non-centered mesh (with respect to the orginin (0,0))
  • elements addition on the fly (in specified directions)
  • coarsening (reducing the number of cells in the whole domain)
• Visualization:
  • Plots of near-tip asymptotic regimes (k-toughness-red, m-viscosity-blue, m-tilde-leak-off-green)
  • Fluid fluxes & velocities as vectors at cell edges
• Export to JSON capability
• Use of the python logging package to log code outputs with different verbosity levels
• Suite of automatic benchmark & regression tests
• Additional examples
• Semi-analytical solution for M-pulse radial HF
• Updated documentation
