This release contains several user experience improvements and bug fixes, as well as access to Sculpt meshing functionality.
(Download Coreform Cubit here.)
New license file required
Due to the completion of our new versioning scheme (see below), the 2021.3 release will require all users to download a new license file from the “My Licenses” section of their Coreform account. This is a one-time occurrence and you will not need to do this again for the remainder of your license term.
Coreform Cubit now follows a Calendar Versioning scheme of YYYY.MM. This versioning scheme was hinted at in the previous release of Coreform Cubit (2020.2), but now is fully in-place. We intend to release new versions of Coreform Cubit with increasing frequency to provide you with quicker access to the latest bug-fixes and new features. We hope you enjoy the March 2021 release: Coreform Cubit 2021.3!
New downloads page
We now provide public downloads of Coreform Cubit—logging into your user account is no longer required for downloading new versions of Coreform Cubit. All downloaded version still require licensing in order to use, of course. However, we hope this change will make it easier to get both the latest release and developer builds and to include Coreform Cubit in your own automated processes.
Latest Development Builds section of the public downloads page contains regular updates of builds that have passed our automated tests. This can be helpful for you to try fresh builds that may contain a new feature or bug fix of interest to you.
Here’s a link to the public downloads page, or find the link on our banner as shown in the image below
Sculpt is back!
Due to an incompatibility, Sculpt meshing functionality was not included with Coreform Cubit 2020.2. We are now nearing completion of a sustainable, long-term solution to this issue, and in the meantime we’ve implemented a short-term fix that has enabled the packaging of Sculpt with Coreform Cubit 2021.3.
This command was created as part of Jason F. Shepherd’s dissertation, Hexahedral Mesh Generation Constraints. The
hexset separate command is designed to create groups containing hexahedral elements based an enclosing set of triangles.
The command is:
Hexset Hex <range> Separate Tri <range> [draw]
For example, given a tri-meshed volume as shown below:
We can create a bounding box and mesh it with hexes:
Then, executing the command:
hexset hex all separate tri in surf 1 2
Export Mixed Mesh Blocks to ANSYS CDB
The ANSYS CDB format supports multiple element types to be defined within a single element block. One of our customers found a bug with our CDB exporter in the case pictured below, so we fixed it! Now you can export meshes to ANSYS CDB that are similar to the single-block, mixed hex-pyramid-tet example shown here.
Graphical User Interface
Components renamed to Plugins
We’re doing some exciting work to enable new functionality in Coreform Cubit. So far we’ve been layering these capabilities on top of Coreform Cubit, using the
Components functionality. However, as we’ve been working we realized that this was a confusing name for a functionality that everyone else understands to be a plugin. So we’ve gone ahead and renamed this functionality
Plugins. This is most clearly seen to the end user through the taskbar, as pictured below.
Added Button to Return Colors to Defaults
We added a Reset to Default Colors button to the Global Geometry Colors options panel, allowing you to easily return to Cubit’s default geometry colors.
