Program Structure:
High-speed automated mesh generation
High quality mesh is automatically generated at a high speed by creating the octree and using the Advancing Front method. Prism layer elements affecting the calculation accuracy can also be created automatically and the layer thickness can be set to link with the width of a flow channel. The software enables faster mesh generation in parallel computing and supports large scale mesh.

Mesh adaptation analysis
With this function in a steady-state analysis, mesh will be automatically refined at an area where the flow or pressure changes greatly. After Solver completes the calculation, Preprocessor is automatically launched and remeshing is executed based on the calculation result. You can generate a coarse mesh first and refine the mesh automatically. The function is useful for an analysis of flows in a tube of a complicated shape.

Modifying CAD data
When CAD data to be used for simulation has a problem, the data can be modified in SC/Tetra. Boundary conditions can be set based on the part names and color information set in the CAD data. When some regions are missing in the model, shapes such as cuboids and cylinders can be added.

Free surface
The function is used to calculate the shape of an interface between a gas and a liquid. VOF method (Interface Capturing Method) enables high-speed calculation with high-accuracy. The function can be used with other functions such as moving boundary, overset mesh, and particle tracking. The function is useful to analyze the effect of waves to a ship and the effect of shaking to a gasoline tank.

Dynamical function, Moving elements
Passive translation and rotation of a rigid object receiving a fluid force can be analyzed. The object can be set to translate and rotate with up to 6 degrees of freedom. The function enables an analysis with a restraint condition (a spring for example) and an analysis of contacting objects. The function can make the simulation result of a check valve more realistic.

Cavitation
The function enables simulation of a vaporization phenomenon called cavitation, which is caused at an area where pressure of a liquid becomes lower than in the surrounding area. The occurrence of cavitation can be predicted by applying the cavitation model based on the pressure values. The software also supports problems caused by cavitation such as erosion.

Moving elements,discontinuous mesh
Flow with motion of objects can be calculated. Motion of objects is, for example, rotation of fans and turbines, and translation such as automobiles or trains passing each other. By combining rotation and translation, various and more complicated phenomena of moving objects can be simulated.    

Overset mesh
By overlapping mesh for a stationary region with mesh for a moving region, a motion which was not able to be simulated using the existing functions such as deformation or rotation can be simulated. In addition, contact of objects and overlap of multiple moving regions are supported. This function is useful to analyze opening and closing of a valve of an engine port, and a gear pump that works with its gears.
