SC/Tetra

The input data (computational mesh, boundary conditions, and material properties) prepared using the preprocessor are read into the solver for computation of the fluid/thermal flow field. The user only needs to specify the name and location of the input file. The solver is equipped with a monitoring function that shows the status of the computation.

Monitor Function

The Windows version of the SC/Tetra Solver uses a monitoring function to indicate the status of the calculations process. The status of basic monitoring indicators can be observed in real-time or the process can be interrupted to confirm more detailed velocity and temperature developments within the calculation domain. Batch processing can be resumed at any time.

Monitor Function

Low Memory Consumption

In general, CFD simulation requires high memory consumption. Therefore, available memory defines maximum mesh resolution, which in turn, can greatly impact calculation accuracy. SC/Tetra is designed to consume less memory enabling it to handle increasingly complex geometries.

Parallel Computing

SC/Tetra's parallel solver is available for further reducing computation time. The increased speed of parallel solvers is especially valuable for large scale models and for transient calculations. The parallel solver is available in various configurations and is optimized for each supported computer Operating System (OS). The Windows version of the parallel solver can be used in the same manner as the standard Windows solver. This enables the user to use parallel technology without any extra knowledge about parallel computing.
