In their own words
ExtendSim
ExtendSim is process simulation software for decision-makers assessing improvement opportunities and system configurations. It supports customizable modeling logic, hierarchical subsystems, interactive user interfaces and exploration of design options. Features include reusable custom blocks, model hierarchies, simulation animation, 35 built-in distributions and statistical analysis tools. Data exchange options include Excel, ODBC and ADO databases, FTP and text files; Scenario Manager can export results to JMP or Minitab. ExtendSim Pro adds discrete-rate and reliability block diagramming capabilities to DE, while DE adds message-based discrete-event architecture to CP. It is a Windows application, with web also listed as a platform. Standard licenses require 64-bit Windows 10 or Windows 11; ARM configurations are not officially supported. Mac use requires installing Windows with an emulator such as Parallels or Boot Camp. The trial lasts 30 days from first launch and is limited to the downloader; it disables Multicore Analysis, watermarks models and cannot run on virtual machines. Individual license options are one-time purchases, with first-year Maintenance & Support included; CP costs $995, paid once, DE $3,495, paid once and Pro $4,995, paid once.
ICEM Surf
ICEM Surf is a curve and surface modeling tool for defining, analyzing, and visualizing complex free-form CAD surface models. It is used in automotive, aerospace, consumer goods, and press-tool design. Its modeling tools and dynamic diagnostics support creating and checking Class-A surface geometry. Listed modules include Professional, Master, Magic, Advanced Tools, Safety Analysis, Scan Modelling, and Immersive VR Review and Realtime Rendering. The Scan Modelling add-on handles dense, ordered, or random point clouds from laser and photo digitizers. Safety Analysis detects sharp edges and corners by simulating a sphere rolling across model geometry. Realtime Rendering supports shadows, environments, materials, lighting effects, and VR design reviews. ICEM Surf supports Windows 10/11 64-bit; its 2026 visualization and rendering requirements specify Windows 11 H2 or newer. It needs at least 8 GB of 64-bit main memory. Commercial pricing is on request, and some interfaces and add-on modules require additional licenses. A free Learning Edition is available after signing in or creating a 3DEXPERIENCE ID, for personal learning only and without support.
