Deploy STAR-CCM+ on supercomputing platform

Recently, there are many platforms that provide supercomputing trials, and many platforms have free trial applications. Due to work needs, I applied for an account on a supercomputing platform and conducted related trials. I made a simple record of the process of deploying STAR-CCM+ software and applications on the supercomputing platform, which also provides a reference for subsequent related applications.

1. Supercomputer platform information

You can log in to the supercomputer remotely through SSH connection. Some platforms also provide webSSH and webVNC connections, which support connecting to the command line or graphical interface through a browser. For specific login methods, please refer to the relevant documents provided by the platform.

Unveiling TenFong Tech’s Domestic CFD Software—QFlux and QMesh

Conclusion first: TenFong Tech’s products QFlux and QMesh do not align with their marketing claims. QMesh is not an “independently developed advanced computational fluid dynamics (CFD) core software,” and QFlux is far from feature-complete. There is strong evidence to suggest that QFlux’s solver may have been “borrowed” from OpenFOAM.

1. Software Overview and Download

Let’s skip the preamble. TenFong Tech’s marketing claims can be seen on their official websites（http://www.tenfong.cn/、http://www.qfx-tech.com/）.

Solver Verification Comparison - Laminar Flow Between Rotating and Static Concentric Cylinders

This paper uses different CFD solvers to verify the laminar flow problem. Verify the accuracy of each solver by listing the operating procedures and differences in the output results of different solvers.

1. Problem description

As shown in the figure below, a fixed-constant laminar flow model between two concentric cylinders is established. The flow is caused by the rotation of the inner cylinder at a constant angular velocity, while the outer cylinder remains stationary. Using periodic boundaries, only a portion of the basin needs to be modeled. The physical model and input data are shown in the following table.
