Creo Flow Analysis - Evaluating Gyroids and Lattices with CFD Webcast Replay

Chapter Summaries

• 0:00 – Welcome & Speaker Introductions: Diane, Rich Moore, Jose Coronado, Tom Quaglia, Alex Jang Diane opens the "Evaluating Gyroids and Lattices with CFD" webinar and Rich Moore introduces the Simerics and PTC presenters along with the agenda covering CFD setup, lattice modeling, and industry use cases.
• 3:48 – CFD 201 Recap: Analyst CFD Embedded in Creo Parametric Rich recaps the 2020 CFD 101/102/201 series and explains how Simerics MP was embedded into Creo Parametric to bring prototype-accurate analyst CFD to designers who need to model the unseen physics inside their designs.
• 5:11 – Creo Flow Analysis Packages: Base, Plus & Premium Overview Overview of the three Creo Flow Analysis packages — Base (fluids, heat, conjugate heat transfer, electronic cooling), Plus (particle, radiation, species, moving/sliding mesh), and Premium (multiphase, multi-component, cavitation, dynamics).
• 6:40 – PTC Digital Thread: Creo Simulate, Vuforia Studio & Windchill Integration Demonstrates how Creo Flow Analysis associatively connects to Creo Parametric, Creo Simulate for fluid-structure interaction, Vuforia Studio for animated streamlines in AR, and Windchill for configuration and data management.
• 8:42 – Simerics–PTC Partnership & Market Adoption Rich covers the Simerics–PTC joint development model, shared APIs, Creo 4 through 10 compatibility, the workflow void filled by Creo Flow Analysis, and rapid three-year adoption bringing analyst CFD to 4.5M+ parametric CAD users.
• 12:03 – What Are Lattices? Bio-Inspired Structures in Creo (Jose Coronado) Jose Coronado, Director of Product Management at PTC, explains bio-inspired lattices — 2.5D, extrusion-based, beam-based, and triply periodic — and how the new Creo lattice feature enables parametric optimization of these structures.
• 14:29 – TPMS Cells in Creo: Gyroid, Diamond & Primitive Deep dive into Triply Periodic Minimal Surfaces (TPMS) — gyroid, diamond, and primitive cells — that are self-supporting when 3D-printed, ideal for shock absorption, biomedical implants, and high-performance compact heat exchangers built via additive manufacturing.
• 17:04 – Automatic Body-Fitted Meshing for Lattices Rich explains how the Creo Flow Analysis automatic mesher body-fits complex lattice geometry with sharp edges and curvy surfaces that would be impossible to mesh manually, making high-end CFD usable for lattice-based designs.
• 18:47 – Y-Mixer CFD Demo: Wizard Workflow Setup (Alex Jang) Alex Jang launches Flow Analysis inside Creo Parametric and uses the guided wizard workflow to set physics (flow, heat, streamlines), materials (air, ideal gas law), and boundary conditions on a symmetric Y-shaped manifold with hot and cold inlets.
• 24:37 – Baseline Y-Mixer Results: The Mixing Problem The baseline simulation reveals a hard thermal interface between hot and cold streams because the symmetric geometry doesn't perturb flow, illustrating why traditional baffles or asymmetric designs are typically required for effective mixing.
• 26:33 – Adding a Gyroid Lattice: Simulation & Streamlines Alex unsuppresses a gyroid lattice created in the Generative/Additive Manufacturing extension, re-meshes with a single Update Project click, and reviews animated streamlines, surface contours, and section views showing dramatically improved mixing.
• 32:03 – Cartesian Cut-Cell Mesh Technology Deep Dive Detailed look at the Cartesian cut-cell body-fitted mesher — cube base cells that split into arbitrary shapes at boundaries, automatic heat-transfer interface creation between fluids and solids, and true "what you see is what you get" mesh quality.
• 35:28 – Production Heat Exchanger Simulation with Dense Gyroid Core Full production heat exchanger example featuring an additively manufactured casing and a dense gyroid core with hundreds of unique flow channels, showing streamlines, mesh quality, section views, and near-uniform outlet temperatures — solved start-to-finish in under an hour.
• 41:11 – Module Deep Dive: Base, Plus & Premium Capabilities Alex walks through use cases per module: Base (internal/external flow, conduction, convection, electronics cooling, e-motors), Plus (radiation via ray tracing, particle erosion, species/microfluidics, moving and sliding dynamic mesh), and Premium (Rayleigh–Plesset cavitation, multiphase/multi-component, fluid-solid dynamics).
• 47:02 – Getting Started, Training Resources & Closing Q&A Rich and Tom Quaglia cover next steps — deeper-dive demos, cloud-hosted Creo workshops accessible via browser, Simerics online training courses, and eight short how-to videos on the PTC Community and Simerics.com — followed by closing remarks.
