Mesh Modification

  V2K provides tools for the modification of the mesh in a local or global context. These controls are accessed via the Solver entry in the main menu bar.

Mesh Interpolation

 The Interpolate option performs algebraic remeshing of surfaces or volumes depending upon the type of visual objects the user has selected. In each case, the index range over which the interpolation is performed is user controllable via the upper and lower slider tabs located in the mesh visualization panel. Results from the remeshing operation are immediately displayed. Note that once invoked the original mesh is overwritten and cannot be restored within the session.

Mesh Smoothing

 The mesh Smooth operation is similar to that described above other than for the fact that the mesh is regenerated via solution to an elliptic set of partial differential equations. All control functions and boundary condition options typically associated with such a process have been hard-coded, so it is again a simple matter of selecting the desired visual objects, setting the desired solution range (in terms of indices) and then selecting the option from the menu. Note that this option recognizes surface visual objects only and intermediate stages of the smoothed mesh are dynamically displayed.

Freeze Plane

 The very first entry in the Solver menu is the Freeze Plane option which enables the user to "fix" a selected mesh plane(s). This facility is typically used to enhance volumetric remeshing with the Interpolate option in that various internal planes, once optimized with the Smooth facility, can be frozen thereby providing a mechanism by which the volumetric mesh can be improved. The impact of the Freeze Plane facility is to subdivide the domain into sections for which the block boundaries and any frozen planes serve as boundary conditions for the algebraic remeshing operation. Planes which have been frozen appear rendered in green.

Mesh Redimensioning

 Under development.

Mesh Redistribution

 Under development.

Mesh Quality

 Though this facility is related to mesh interrogation rather than mesh modification, it has been included within this menu as it also performs calculations upon the mesh. A detailed explanation of the mesh interrogation facilities is provided elsewhere in this document.
