The different surface and volume meshing models which constitute the meshing pipeline in STAR-CCM+ are introduced. Day two focuses on the basics of mesh generation – principles and strategies for efficient computational solving.We describe the architecture of the software and the advantages of the client-server approach before moving into an introductory example that moves from problem import to a review of simulation results and an introduction to post-processing. During the first part of the day, we discuss and present the conceptual elements of flow fluid simulation moving on to describe how these elements are represented in the workflow process of STAR-CCM+.Visit our store to learn more and purchase the target. The Imatest Sinusoidal Siemens Star chart is produced on matte paper and is available at various sizes. This target will be particularly useful for security and automotive industries where extreme processing is commonplace and RAW sensor data is difficult to obtain. The Imatest version of the chart includes registration marks for automatic region detection and slanted edges for convenient MTF comparison. Slanted-Edge versus Siemens Star contains a detailed comparison of results. The Siemens Star is included in the ISO 12233:2014 standard along with the slanted-edge and hyperbolic wedge, all of which are supported by Imatest modules. When placed off-axis, the chart will have segments that cover sagittal and tangential directions in addition to vertical and horizontal directions.
Since the Imatest Star module analysis is extremely noise-resistant, measurements are highly repeatable. Siemens star MTF20 (the spatial frequency where MTF is 20% of its low frequency value) is a good estimate of limiting resolution. The Sinusoidal Siemens Star test chart allows you to measure MTF and limiting resolution with a chart that provides angular response and may be less affected by signal processing (especially sharpening) than slanted-edges.
