Best practices

  • Always use fracture-energy-based evolution with characteristic length
  • Understand the solver-specific characteristic length definition
  • Use reasonable element aspect ratios — avoid highly distorted elements
  • Verify mesh objectivity with two mesh densities — results should be similar
  • If mesh-dependent: check characteristic length, evolution law, element quality
  • Document the regularisation method and the objectivity verification
