This error message is usually the result of General to Mesh to Check operation, and the error message is shown in the console (TUI) window. Below are some areas to check to determine better why you see failures.ġ. After that, we'll take a deeper dive into meshing modes and options.įrom time to time, you may find that your model is failing to mesh, or you'd like to understand in more detail why your mesh check is failing. But, just in case you're here because of a specific error, we want to provide some tips and tricks around common errors and troubleshooting first. To see this part mesh instancing behavior in action, check out this short YouTube video.In this article, we plan to provide some of the basics and best practices you'll need to know for meshing in Fluent. Look through the CAD Integration > File Format Support section in the documentation:Įach file type that can be imported by ANSYS is discussed in detail here, with each type giving the user information on instancing support, geometric entity support, smart updating, etc.
The ANSYS Help documentation goes into good detail on what CAD systems support instancing, along with the many other options available on geometry import. Here is a list of the major CAD systems that ANSYS supports instancing from:Įven some CAD neutral files support instancing when read into ANSYS: IGES and Parasolid. ANSYS can take advantage of this very easily… so much so that using part instances is the default behavior in ANSYS. One part file is used multiple times this is the concept of instancing. One part that is copied around an assembly multiple times does not have a part file for every copy.
If CAD models are pulled from a major CAD systems, odds are the concept of instancing is not foreign to the user. What if the number of bodies/faces/even edges is larger? Select the 20 bodies that those 20 faces belong to for a mesh method… Select 20 of the exact same face in a bolt circle to specify the number of elements on an annulus…
In cases where components are reused multiple times in an assembly, the meshing can be tedious.
Repetitive meshing tasks can be a significant portion of the time a user spends setting up an FEA model for simulation.
