Program Structures:
Various methods to represent shapes
The shape of a model to be analyzed can be represented by using the following methods: voxel method (slanted faces and curved faces are represented in staircase patterns), cut-cell method (the shape of a model created with a CAD tool can be represented more accurately), and overset mesh method (a model of an arbitrary shape defined with unstructured mesh can be overlapped on a model defined with structured mesh to use the shape created with a CAD tool as is).

Large-scale calculation
In structured mesh, even a complicated model does not need to be modified almost at all and the shape or the scale of a model does not affect the difficulty of mesh generation. In addition, Solver performs a calculation at a high speed in parallel computing and achieves effective processing as the speed increases depending on the number of subdomains.

Moving objects
A flow generated by a moving rigid object can be calculated. Conditions including the motions of an object (translation, rotation, and elastic deformation), heat generation/absorption, and air supply/return can be set. The model of a moving object is created on another mesh. In this way, conditions such as the distance that the object moves are limited very little.

Parametric study
Parametric Study Tool is useful to apply multiple conditions to multiple parts and compare the analysis results. The tool automatically performs calculation the required number of times only by specifying the number of conditions and the parameters of the conditions. Multiple analysis results of different conditions can be obtained easily by setting parameters simply at the early stage. In addition, the tool can reduce human errors, which tend to be caused when multiple models are created.

Multiblock
Mesh can be refined partially to represent a model shape more accurately and perform a calculation more efficiently.

Customizing variables
Complicated conditions including trigonometric functions and conditional branches such as IF statements can be set without compiling.

Part library
The shapes and conditions of frequently used parts can be registered. Conditions include the allocation position, material, and heat generation.
