Model Building & Mesh Generation

Model Building Features

APUS-CFD provides a powerful model-building facility that can be used to create user-defined objects and assemblies. An assembly can be created from built-in objects or by existing subassemblies (from a library) or by importing a number of STL files. When you finish with your model-building you can save your model as a 'scene' or as another 'assembly'.

Comprehensive object shapes, including rectangular blocks, cylinders, spheres, prisms, pyramids, and more
An 'explorer' style browser providing a logical hierarchical view of the model with user-selectable number of levels of assemblies and subassemblies
Ability to multiple select objects and assemblies and attach boundary conditions
A mouse-driven interactive environment for moving and sizing objects and assemblies
3D view manipulation with dynamic rotation, translation and zoom
Geometry import using STL file format

Fully Automatic Mesh Generation

APUS-CFD provides a fully automatic Mesh Generation module (APUS-Hexa) for the creation of hexa-dominant unstructured meshes. Having built a model, using the model-building facilities, it is a matter of few mouse clicks to generate the mesh. Alternatively, you can import one or more STL files and generate automatically a volume mesh or a surface mesh.

APUS-Hexa is an invaluable tool for the creation of high quality meshes from very complex geometries. The task of mesh generation has been simplified and the need of creating time-consuming surface meshes has been eliminated. Some of the features of APUS-Hexa are:

Direct interface to most CAD systems by using STL-file format
Imported STL need not be watertight and no requirement for tedious clean-up procedures
Good mesh quality guaranteed, resulting in fast converged solutions
User input is minimum
Local mesh refinement is provided
Fast algorithms reduce the turnaround times by orders of magnitude, compared to other conventional mesh generators
Robust and simple in its operation
