CAESES 2026.1 Win/Linux64 – Parametric Geometry Modeling and Shape Optimization Software for Simulation-Driven Design

CAESES is a specialized CAD and optimization platform developed by FRIENDSHIP SYSTEMS, designed specifically for parametric geometry modeling, shape optimization, and preparation of simulation models for CFD. Unlike traditional CAD software, CAESES is purpose-built for simulation-driven design (SDD), enabling engineers to create fully parametric models and automatically generate hundreds of design variants from a single parameterized baseline.

A key differentiator is CAESES’ deep integration with CFD and CAE solvers, including ANSYS Fluent, CFX, STAR-CCM+, OpenFOAM, Cadence Fidelity CFD, NUMECA, and many others. This enables automated workflows spanning geometry generation, meshing, simulation execution, result extraction, and multi-objective optimization. The software’s ability to explore large design spaces and optimize complex shapes before physical prototyping makes it indispensable for industries like marine engineering, turbomachinery, automotive, aerospace, and energy.

The 2026.1 release introduces a new Python API, supports the latest major CFD solvers and CAD kernels, and delivers user experience improvements that make it faster and more intuitive to design and optimize complex geometries.

 

Primary Users

CAESES 2026.1 is designed for design engineers, CFD specialists, naval architects, aerospace engineers, and turbomachinery experts who need to integrate parametric geometry modeling with simulation-driven optimization . It serves professionals who:

  • Design and optimize complex geometries for marine propellers, pumps, turbines, compressors, and aerodynamic surfaces

  • Perform simulation-driven design by automatically generating and evaluating thousands of design variations

  • Streamline CFD workflows by automating geometry preparation, meshing, simulation execution, and result extraction

  • Conduct multi-objective optimization to balance competing performance criteria like efficiency, weight, cost, and pressure drop

  • Explore extensive design spaces using Design of Experiments (DOE) and advanced optimization algorithms

Key Features & Capabilities

Parametric Geometry Modeling

Create fully parametric 3D models that can be automatically adjusted by changing a few key parameters, generating hundreds of design variations in seconds. CAESES uses a feature-based approach where each geometry feature has associated parameters that can be linked to optimization variables.

CFD Integration and Automation

CAESES communicates directly with leading CFD solvers (ANSYS Fluent, CFX, STAR-CCM+, OpenFOAM, Cadence Fidelity CFD, and more) to automate simulation workflows. The software handles geometry generation, meshing (including mesh morphing), simulation execution, and post-processing with minimal manual intervention.

Shape Optimization

Optimize geometries for maximum efficiency, minimal pressure drop, reduced drag, and improved aerodynamic/hydrodynamic performance. CAESES supports both single-objective and multi-objective optimization, allowing engineers to balance competing design criteria like performance, weight, and cost.

Design of Experiments (DOE)

Explore the design space efficiently by systematically varying parameters and analyzing their impact on performance metrics. DOE helps identify the most influential parameters and reduces the number of simulations needed for optimization.

Design Space Exploration

Evaluate thousands of design candidates automatically to identify optimal parameter combinations. CAESES uses advanced search algorithms to navigate complex, multi-dimensional design spaces effectively.

Automation and Customization

The new Python API in 2026.1 provides complete programmatic control, enabling fully automated design processes. CAESES can be integrated with other tools and run in batch mode for high-throughput optimization campaigns.

Cross-Platform and High-Performance

Available for both Windows and Linux (64-bit) platforms. Linux support is particularly valuable for integration into HPC environments for large-scale optimization runs. The software is optimized to handle large design spaces and complex geometries efficiently.

What’s New in CAESES 2026.1

The 2026.1 release introduces several important enhancements:
