Review Questions

• How does ANSYS facilitate the analysis of biological structures in computational biomechanics?
  • ANSYS enhances the analysis of biological structures by allowing engineers to create detailed models of tissues and organs that mimic their physical properties. Through finite element analysis (FEA), users can apply various loads and boundary conditions to these models to predict how they respond to mechanical forces. This capability is crucial for applications like implant design or assessing injury risks in biomechanics.
• In what ways does mesh generation impact the accuracy of simulations conducted with ANSYS?
  • Mesh generation significantly affects the accuracy of simulations in ANSYS because it determines how well the geometry of a model is represented. A finer mesh can capture more detail but requires more computational resources, while a coarser mesh may lead to quicker simulations but less accuracy. The balance between mesh density and simulation efficiency is critical for obtaining reliable results in engineering analyses.
