Isolate and defeature the separator by removing tube-shaped objects under 3 mm, repair holes with the fill hole command, and delete non-fluid-domain parts using PID selection.
Close outer openings, seal inlet and outlet with planar surfaces, then classify and delete exterior surfaces using isolate exterior to reveal inner faces.
Use topo to connect components, switch tolerance from middle to draft for larger match distances, repair hot points, and fill holes before closing with planar surfaces.
Trim surplus from top and bottom, close gaps, and delete undesired faces to refine the geometry; project hot points and apply zone cut to create a watertight ANSA model.
Create a surface mesh with CFD auto spacing, set min 0.5 and max 2 mm, and apply reshape and manual edits to fix edges and achieve volumetric meshing readiness.
Create a volume mesh for CFD with boundary layers and correct orientation, generate two layers, use tetra rapid elements, convert to poly to reduce cells, and save in Fluent format.
This course is designed for intermediate ANSA users who want to dramatically improve their efficiency and workflow. Instead of scattered tips, you’ll follow a structured, step-by-step example that demonstrates best practices and practical techniques used in real engineering scenarios.
By the end of the course, you will understand how to properly configure CAD import settings to avoid downstream issues and save time during preprocessing. You will learn effective methods for geometry cleanup and healing, ensuring your model is simulation-ready without unnecessary manual effort. The course also covers techniques for extracting inner surfaces, helping you handle complex geometries with confidence.
You will gain the ability to build a fully airtight computational domain, a critical step for accurate CFD simulations. In addition, you’ll master surface mesh preparation, including quality control and optimisation strategies that prevent common meshing problems. Finally, you will create high-quality volume meshes suitable for reliable analysis.
Overall, this course equips you with a streamlined, professional workflow that reduces trial-and-error and helps you operate at a significantly higher level in ANSA.
