This initially led us to a better understanding of how we should apply Global and Local Mesh Controls. In our first posts on Mesh Sizing we explained that as well as capturing all key features of the geometry (using local sizing and the curvature size function), we also need to have a sufficiently fine mesh to adequately capture regions where the flow will experience rapid change in key variables such as pressure, velocity or temperature. Let's take this opportunity to explain exactly why inflation layers are a critical component of a good CFD mesh and how we can create them easily within ANSYS Meshing. All rights reserved.Throughout our first set of Tips & Tricks posts relating to meshing controls and meshing methods, we have made mention of Inflation Layers a number of times. If you are using an earlier version of ANSYS, send the design to ANSYS. If you are using ANSYS 13.0, click Update Parameters in the ANSYS group on the Prepare tab. It is helpful to rename the groups with a prefix that tells you the group's type, because named selections and driving dimensions are grouped together in the structure in ANSYS. If you are using ANSYS 13.0, the new group is automatically added to the Parameters group in Workbench.

Information such as Selection, Alt+selection, move anchoring, axis, and ruler dimension is all stored with the group. You create a group from any set of selected objects. You can use the Selection panel to select objects in the same part that are similar or related to the object that is currently selected.Ĭlick Create Group in the Groups Sets of objects that appear in the Groups tab. Select the objects you want to include in the group. See Using groups to drive changes in ANSYS for information about using groups to make changes to the design in ANSYS. You can create named selections in the SpaceClaim Groups panel and then use these groups as named selections in ANSYS. You are here: SpaceClaim add-ins > ANSYS add-in > Using named selections in ANSYS
