Overview
PTC Creo
PTC Creo is a scalable 3D Computer-Aided Design (CAD) suite that helps you take products from concept to digital prototype with precision. You can build complex geometries, manage large assemblies, and create detailed manufacturing drawings within a single environment. It addresses the needs of mechanical engineers and designers who require high-fidelity modeling and integrated simulation to validate performance before physical production begins.
You can optimize your designs using AI-driven generative design and verify structural or thermal integrity with real-time simulation tools. The platform supports your entire development lifecycle, from initial sketches to CNC machining and 3D printing. Whether you are designing consumer electronics or heavy industrial machinery, you can reduce errors and speed up your time-to-market by using its associative data model that updates downstream deliverables automatically when you change a design.
SimFlow
SimFlow is a powerful computational fluid dynamics (CFD) platform that brings the capabilities of OpenFOAM to a user-friendly graphical interface. You can handle complex engineering challenges including compressible and incompressible flows, heat transfer, and chemical reactions without writing code. It allows you to import geometry directly from CAD software, create high-quality meshes, and monitor simulations in real-time to ensure accuracy and efficiency.
Whether you are designing automotive components or optimizing HVAC systems, the platform provides the tools to visualize flow patterns and pressure distributions effectively. You can run simulations on your local machine or scale up to high-performance computing clusters for massive datasets. It is designed for engineering professionals and researchers who need the precision of open-source solvers combined with the speed of a modern, intuitive workflow.
Overview
PTC Creo Features
- Parametric Modeling Create 3D models where changes to one part automatically update your entire assembly and related engineering drawings.
- Generative Design Specify your design requirements and let AI-driven tools automatically produce high-performance, manufacturable geometries for you.
- Real-Time Simulation Get instant feedback on structural, thermal, and fluid flow performance as you edit your geometry in the modeling environment.
- Additive Manufacturing Design, optimize, and validate complex lattice structures and print checks specifically for 3D printing without leaving the software.
- Model-Based Definition Embed all necessary manufacturing information directly into your 3D model to eliminate the need for traditional 2D paper drawings.
- Direct Modeling Edit geometry quickly and intuitively even if you didn't create the original file, making it easy to handle multi-CAD data.
SimFlow Features
- Mesh Generation. Create high-quality hex-dominant meshes automatically for complex geometries using the integrated snappyHexMesh and cfMesh tools.
- Multiphase Flow. Simulate interactions between different fluids, such as water and air, to predict cavitation, splashing, or free-surface movements.
- Heat Transfer. Analyze conduction, convection, and radiation within your designs to optimize cooling systems and thermal management strategies.
- Real-time Monitoring. Track residuals and physical quantities during the calculation process to catch errors early and save valuable computing time.
- Parallel Processing. Speed up your simulations by distributing the workload across multiple CPU cores with seamless MPI support.
- Post-processing. Visualize your results with integrated ParaView support to create stunning animations and detailed vector plots of fluid behavior.
