Read how Pointwise and ISimQ have developed a new mesh adaption process that achieves the hopes and promises of adaption from long ago by removing mesh generator skill from the CFD analysis process to produce consistent, high-quality simulation results.
Several new significant features have been added in our latest version, Pointwise V18.4. In this Q&A, our Product Planning Team will answer questions about the new features, the future of computational fluid dynamics (CFD), and the Pointwise development plan.
Improve CFD simulation efficiency and accuracy using solution adapted meshing. In this webinar, we detail the process for developing a solution-based mesh adaptation schema. Solution driven mesh adaptation can accelerate the convergence rate by 50 percent or more, while simultaneously reducing estimated error by an order of magnitude.
Improve CFD simulation efficiency and accuracy using solution adapted meshing. Watch this recorded Let’s Talk Meshing Live Q&A session to learn how mesh adaptation can help make your CFD process more efficient and accurate.
A team of engineers at CRAFT Tech set out to model an experimental supercritical carbon dioxide (S-CO2) compressor configuration. The engineers needed software that would resolve flow gradients with a minimum number of grid points and be flexible enough to provide the best grid for each region of the machine that they were modeling. They found both these solutions in Pointwise.
Read the case study, "Hybrid Meshing Key to Improving CFD Simulation Efficiency," which summarizes how a T-Rex hybrid grid showed up to a seven-fold improvement in solution efficiency compared to other approaches in predicting thrust and torque for a marine propeller.
There are two primary challenges associated with the degree elevation of linear elements: boundary conformance and curving of high aspect ratio cells encountered within the boundary layer region. In this webinar, we address these challenges and show how to improve CFD solution accuracy by generating boundary conforming, high-order meshes.
Learn the skills and techniques to efficiently create multi-block structured grids for turbine blades from start to finish. This video includes discussions about which topologies work best and how to create them as well as how to avoid common problems.
Three meshes (multi-block structured and unstructured with hexahedral and prismatic boundary layers) were generated for a generic volute and simulations were performed in the Code Leo CFD solver. Meshing time, solution time, and solution accuracy are compared.
Using a generic, baffled tank stirred by a Rushton turbine you will see how to use Pointwise to generate high-quality unstructured meshes suitable for steady-state moving reference frame calculations in OpenFOAM.
Pointwise can easily manage and organize complex assemblies so you can focus on meshing a single component at a time. This allows engineers to rapidly generate high quality hybrid grids while maintaining the connectivity between adjacent components.
Combustion Research and Flow Technology (CRAFT Tech) has been using CRUNCH CFD® and Pointwise to design and evaluate pump systems for our customers. Pointwise has proven to be a robust and powerful tool for generating high-quality unstructured meshes.
At Syracuse University, a mixed group of both graduate and undergraduate students had the opportunity to participate in a project involving an innovative new wing design. Overseen by Prof. Thong Dang, the team sought to analyze this new design to determine its practicality and effectiveness.
This two-part video is aimed at providing guidance in creating a CFD ready viscous multiblock structured mesh for a single passage of a high stagger angle axial rotor geometry.
