RortexUTA is a set of FORTRAN Codes and a Tecplot script version for vortex identification and related vortex and turbulence research. The software was developed by Yisheng Gao, Shuling Tian, Xiangrui Dong and Chaoqun Liu and Yisheng Gao is the major contributor to the software.

Once the signed User Agreement is received, the link to download the software will be emailed along with the password.
Liu et al. proposed a new vortex identification method - $\Omega$ method, which has a relatively unique threshold $\Omega=0.52$ comparing with traditional $Q$ and $\lambda_2$ methods and is able to capture weak and strong vortices at the same time.
Message From Director
Dear Friend:Welcome to the web page of the Center for Numerical Simulation and Modeling at the University of Texas at Arlington.
The Center for Numerical Simulation and Modeling (CNSM) at the University of Texas at Arlington is an interdisciplinary research group composed of faculty members from Mathematics, Statistics, Biology, Mechanical Engineering, Aerospace Engineering, Physics and other Departments.
CNSM uses resources to develop a nationally and internationally recognized center for world-class research, technology transfer, and innovative opportunities for higher education.
The center has actively encouraged world-class research on many challenging problems, such as high-order shock capturing scheme, adaptive grid generation, multigrid, parallelization, direct numerical simulation (DNS) and large eddy simulation (LES) for flow transition, turbulence,shock/boundary-layer interaction, cooling, combustion, chemical processing, design optimization, and environmental protection.
The NSM center is actively involved in a very strong PhD Program in Applied Mathematics in order to meet very positive job market needs from US industries.
Your interest in our research is highly appreciated.
