# ANSYS vs ABAQUS vs COMSOL - So Sánh Phần Mềm FEA Chọn phần mềm FEA phù hợp là quyết định quan trọng cho dự án simulation. ## ANSYS Workbench ### Ưu Điểm: - **User-friendly** interface - **Integrated** CAD tools - **Strong** structural analysis - **Good** documentation ### Nhược Điểm: - **Expensive** licensing - **Resource** intensive - **Limited** customization ### Best For: - Structural analysis - Thermal analysis - Beginner users - Industry standard ## ABAQUS ### Ưu Điểm: - **Powerful** nonlinear solver - **Advanced** material models - **Excellent** contact analysis - **Customizable** via scripting ### Nhược Điểm: - **Steep** learning curve - **Complex** interface - **Expensive** ### Best For: - Nonlinear analysis - Advanced materials - Research applications - Expert users ## COMSOL Multiphysics ### Ưu Điểm: - **Multiphysics** coupling - **Flexible** physics setup - **Good** meshing tools - **Parametric** studies ### Nhược Điểm: - **Very expensive** - **Steep** learning curve - **Resource** heavy ### Best For: - Coupled physics - Heat transfer + fluid flow - Electromagnetic analysis - Research & development Các bạn đã dùng phần mềm nào? Chia sẻ kinh nghiệm nhé!

Excellent tips! Về **Mesh Quality**, mình thường check: 1. **Aspect Ratio** < 3:1 cho structural analysis 2. **Skewness** < 0.7 (tốt nhất < 0.5) 3. **Jacobian** > 0.6 Với ANSYS Mechanical, **Patch Conforming Method** cho geometry phức tạp, **Patch Independent** cho simple parts.

Về **Boundary Conditions**, một số lưu ý: - **Fixed Support**: Chỉ dùng khi thực sự cần thiết - **Remote Displacement**: Tốt hơn cho bolt connections - **Contact**: Bonded vs Frictional vs Frictionless **Von Mises Stress** công thức: σ_vm = √[(σ₁-σ₂)² + (σ₂-σ₃)² + (σ₃-σ₁)²]/√2
