Surface Wrapper Properties
This section describes the properties that you can set for the Surface Wrapper.
The surface curvature and surface proximity properties are common to several meshers, and as such are documented in Surface Mesher Controls and Values.
| Per-Part Meshing | Activating Per-Part Meshing causes Simcenter STAR-CCM+ to wrap each part individually. In this case, results are stored as a new description for each part. There are no new parts as is the case when wrapping all parts at once. Any interfaces previously defined will be ignored causing the mesh between connected parts to be non-conformal. This option is useful if the Trimmed Cell Mesher or Thin Mesher can not produce a mesh at the interface. When the Per-Part Meshing box is deactivated all input parts will be wrapped at once and the wrapper results are stored in a new part. No new description is created. | |
| Mesher Execution Mode | For
surface wrapper operations the Mesher Execution Mode is ignored
except when you set this property to Concurrent. For both Serial and Parallel
execution modes, the Surface Wrapper runs in
Parallel using either distributed memory
parallelism (default) or shared memory parallelism (Legacy Wrappr
activated). The Surface Wrapper only runs in serial when using the
Concurrent execution mode. For more information, see Surface Wrapper. |
|
| Input Parts | Specifies the geometry parts for which the operation generates a mesh. | |
| Perform Curvature Refinement | Activating Curvature Refinement increases the number of faces based on surface curvature or deviation distance. | |
| Perform Proximity Refinement | Activating Proximity Refinement increases the number of faces based on the distance to nearby surfaces. | |
| Perform Gap Closure | Activating Gap Closure can automatically close holes in the surface that are either smaller than a user-defined size, specified by seed points, or both. | |
| Perform Mesh Alignment | Selecting the Perform Mesh Alignment option allows the mesh alignment location values to be set. That is, a wrapper mesh line can be "pinned" to a given value in any of the X, Y and/or Z directions. | |
| Create Weak Contacts With Input Parts | Activating the Create Weak Contacts With Input Parts option when the Per-Part Meshing option is deactivated creates new weak contacts. The weak contacts that are created do not result in a conformal mesh. However, when you assign parts to regions, these contacts are converted into interfaces which the solver then uses to make the mesh conformal. | |
| Perform Partial Wrapping | Allows you
to exclude surfaces which do not require surface wrapping from being
wrapped in a Surface Wrapper operation. Surfaces that are excluded
from wrapping in the Surface Wrapper operation are copied from the
original geometry and fixed to the wrapped surfaces. See Setting the Volume of Interest and Wrap
Properties. Partial wrapping requires the Legacy Wrapper. |
|
| Legacy Wrapper | Activate
this option only if you require partial wrapping or local surface
wrapping. For all other cases you can leave this option
deactivated. The Legacy Wrapper always uses shared memory parallelism, except when you set the Mesher Execution Mode to Concurrent. For more information, see Surface Wrapper. If you load a simulation that was set up in Simcenter STAR-CCM+ 2306 or older, this property is activated by default. |
|
| Output Part | Specifies the name for the output part, this can be changed by renaming the wrapper operation node. This property is disabled when Link Output Part Name is deactivated | |
| Link Output Part Name | Allows you link the name of the wrapper operation node and the generated part node under . | |
| Perform Local Surface Wrapping | Allows you
to specify surfaces where you want to perform local wrapping on
using the Local Extents node. For more
information, see Refining the Wrap. Local wrapping requires the Legacy Wrapper. |
|
| Run Global Wrap if Local Fails | Causes
Simcenter STAR-CCM+ to execute a global
surface wrap if the local wrap fails. This option produces a valid
wrapped mesh and is intended for use in a fully automated batch run
or design study, so that a wrapping failure does not halt the
process. This option is not selected by default due to the high computational cost of running the global wrapper. |
|
| Verbose Output | Activating Verbose Output prints more verbose output to the Output window during Meshing. | |
