This tool is located in the mesh menu for all user profiles. It is useful utility to fill the holes and feature loops. It works for 1st order tria or quad elements. The selection makes it easier to fill the holes for selected components. It is an automated utility to fill the holes within selected components or elements. You can manually fill the holes using node/free edges selection.

The Merge and Disconnect tools are located in the Utility tab.

The Mesh Control browser is located in the Mesh menu for all user profiles.

Mesh controls provide the capability to automate and streamline the meshing process for surface meshers, adaptive wrapper and volume mesher in one browser. Using mesh controls enable you to define mesh settings for all of the entities that need to be meshed in one meshing job.

New multithreaded mesher, similar to surface deviation to remesh the elements is now available. It can be accessed via mesh controls. It captures curvature and provides smooth transition from smaller sized elements to larger sized elements. The new mesher internally identifies the elements features based on defined feature angle and captures and refines them. It provides the capability to refine the mesh based on proximity and angles specification. You can define any additional features to be captured and refined.

New options to refine 2d mesh based on the proximity, angle and shapes are added and can be accessed through mesh controls along with surface deviation meshers.

Proximity based refinement:

Provides the capability to refine surface or elements mesh based on proximity. It automatically identifies close proximity areas and refines elements based on user specification. You can define refinement based on refinement size, element size/gap ratio or through refinement curve.

Angle based refinement:

Provides the capability to refine surface or elements mesh based on angle between surfaces or element faces. It automatically identifies refinement candidates and refines elements based on user specification. You have control over angle limits and refinement size.

Shape based refinement

New capability to refine 2D mesh based on shapes with refinement zones. Refinement zones can be accessed within the Mesh Control browser.  You  can define box, sphere, cone, frustum, cylinder for refinement. Graphical objects provide better idea of shape definition and location. Refinement zones are used to refine mesh with a defined size. Refinement zones are also supported for surface meshing (surface deviation only), adaptive wrapper, and volume meshing.

New functionality has been added to the existing wrapper to wrap the cavity as well. With the same wrap settings, you can choose to perform exterior wrapping or cavity wrapping.

New capability to define localized wrap settings via the Mesh Control browser. Local controls will take the precedent over global settings.

New functionality to define which volumes to be wrapped is introduced. This functionality can be accessed in the Model Adaptive Wrapping Mesh Control. You have the option to wrap all the volumes, nth largest volumes, volume enclosed by seed node or exclude volume enclosed by a seed node.

Performance of wrapping is improved in this release. Feature capturing algorithm is much faster compared to 13.0.110. Few function is also multithreaded.

New functionality is added to define source and target seed node for wrapping. Now you can define the enclosed node and target areas where leak checking is required. Multiple target points can be defined. It is a very useful visual utility which help to seal desired cavity. If the leak is identified, patching the gaps can be done by Fill-hole Patch tool or by increasing gap patch tolerance.

Performance of boundary layer meshing is significantly improved in this release. 55 mi BL Penta BL elements can be generated in one hour on a full scale external aero problem compared to 5 hours in 13-110. Boundary layer meshing is completely multithreaded.

New capability to define localized boundary layer settings. User can define local BL settings for desired element set or components in mesh control browser. Local controls will take the precedent over global settings.

New capability to define growth rate based on desired aspect ratio. This option enables the growth rate definition for boundary layers to be based on the defined aspect ratio of the final layer. After the first few initial boundary layers, if this type of growth rate method is selected, the rest of the BL will grow to achieve the user-defined Final layer height/base ratio.

New capability to define BL acceleration for boundary layers. You have the option to start the accelerating BL growth after few BL layers. This option will provide the capability to achieve faster BL- tetra transition.

This feature enables you to define 1st layer height as a factor of input 2d element size. This option is useful when the size of 2D elements varies significantly and a constant first layer height is not needed. With this factor, a smooth BL to tetramesh transition for large variation in 2d element size.

New functionality to define which volumes to mesh and option to define solid and fluid volumes before meshing has been introduced. This functionality can be accessed in the Mesh Control browser. You have the option to mesh all the volumes, largest volumes or volume touching reference elements. While selecting volume touching reference element, you can distinguish fluid and solid volume as well.

This features provides new functionality to output boundary layer contours after volume meshing. This new capability provide better options for reviewing boundary layer mesh rather than masking elements or creating cross sections. You can define the option via the Volume Selector in the Mesh Controls browser. After meshing, you can load the .res file to visualize the contours of first layer BL height, number of layers generated and total boundary layer height on entire model.

New capability to import AcuSolve solver settings as well while importing .inp file has been introduced. While importing AcuSolve solver decks (.inp file) the defined parameters in the solver deck will also be imported in the model and can be accessed via the Solver browser. Any unsupported parameter will be collected in “Unsupported Entries” under each folder category of the  Solver browser. You can manually edit those entries and the modified values can be exported.
