Traditionally, the most time consuming part in complete CFD process is creating a good quality mesh. Considering the advancements in meshing techniques available in today’s meshing tools, lot of automation of meshing algorithm is done. The main bottleneck is making CAD geometry mesh ready or converting dirty CAD to clean mesh-able CAD. All meshing algorithms needs a water tight geometry (defined within the constraints of the tolerance considered by meshing software). Creating a clean watertight geometry from dirty CAD is sometimes challenging and in most of the cases very time consuming job.

In this tutorial we are going to learn about ‘Fluid Domain Extraction’ techniques using ANSYS ICEM CFD. We are going to learn two techniques, one the orthodox way and other the smart way.

Are you a CFD engineer? Have you ever faced trouble doing meshing because of CAD issues like complexity in CAD model and CAD data loss while importing CAD geometry in CFD tools? Do you want to know how to do CAD repair and how to get geometry ready for analysis? Its necessity, process and how to do CAD-Repair? Being a CFD analyst do you want to know how to extract CFD domain and how to simplify the task of creating good quality mesh that is required for CFD analysis?

Knowing about the grid generation process as discussed in our earlier blog, Grid Generation for CFD Simulation: Introduction, we have seen what is a mesh, how a mesh is created using a software, what are mesh types etc. However once a mesh is created the challenge remains to assure that a given mesh is good & would generate accurate results. So there are some terminologies associated with mesh quality & let us know them.
