Civil Engineering

Super-tall buildings, façades systems, façade manufacturing, free form structures and protective designs – The challenges of designing and building the world’s most daring and innovative structures can be solved using Altair technology to create beautiful, functional and lasting designs. Civil engineers gain insight throughout the development process to rapidly evolve designs, control costs and ensure structures are safe and feasible. Architectural teams can unleash their creativity and see their concepts validated quicker and with fewer design iterations, while structural teams enhance their design process with automatic optimization workflows to achieve maximal performance. Simulation tools help model and accurately predict the unique behavior of advanced composite materials and optimize their shape and manufacturability to meet performance and cost criteria.

Optimization Inspired by Nature

Optimization Inspired by Nature

Finding more efficient shapes, reducing material and weight, and increasing stability is vital to civil engineers. To meet these challenges, designers and engineers leverage topology optimization. This process follows the patterns of material growth in biological forms to eliminating material redundancies within prescribed performance targets and create optimized structures. Size optimization is a critical component, deployed within 1D models to optimize beams and columns.

Unleashing the Power of Digital Wind

Unleashing the Power of Digital Wind

When building the world’s largest skyscrapers and high-rises, it is imperative to consider the impact of wind pressures on the structure and on pedestrian comfort. Virtual wind tunnel testing is now globally recognized as a mature technology that produces accurate modeling of wind pressures, delivers rapid results, and enables designers to explore and evolve concepts based on CFD insights.

Resilience Against Blast Events

Resilience Against Blast Events

For more than 30 years, Altair has established itself as a leader and industry standard for blast and explosion effects and high velocity impacts for risk mitigation. These tools enable civil and material engineers to simulate these events, predict damage, identify structural vulnerabilities, and optimize the design for maximum structural integrity under extreme loads. Faster and cheaper than destructive tests, engineers gain valuable insights yielding the design of safer structures.


Practice High-performance Design

Altair has developed a multi-disciplinary optimization workflow that allows clients to understand structural performance sooner, accelerate design cycles to reduce cost, and virtually validate designs to reduce risk. High-performance design is a holistic approach for developing feasible, safe and robust structures with a simulation-driven approach.

Altair’s repeatable and customizable workflow combines wind loads with most advanced optimization techniques. The cost and time to deliver complex steel structures can be reduced thanks to automatic workflows capable of integrating all the major AEC structural solvers via direct link or neutral file formats, the power of size optimization for steel sections in 1D models, and topology optimization for 3D models to find the optimal load path.

Fast Alternative Design with Mesh-free Solver

Architecture, Engineering, Construction (AEC) design cycles have two crucial requirements: product performance and timely delivery. Due to immense project pressures, there is often insufficient time to investigate design alternatives or new solution. Altair SimSolid™ is a technological breakthrough that allows civil engineers to analyze fully featured CAD assemblies in minutes, eliminating geometry simplification and meshing. These insights allow engineers to foresee better alternatives in large structural models and rapidly evolve designs within existing project timelines. With SimSolid, design teams can perform multiple iterations of their most complex parts and explore multiple alternatives of large assemblies at blazing speed.

Aerodynamic Insight from Design to Validation

Computational fluid dynamics (CFD) has become a powerful tool deployed throughout the AEC design workflow. For designers, concept-stage aerodynamic simulation helps shape designs to uphold the client’s vision while adhering to downstream performance targets.

Using digital wind tunnel testing, it is now possible to investigate multiple design alternatives to determine feasibility and update shapes on the fly. For detailed validation in the latter stages of development, Altair CFD tools provide a granular understanding of aerodynamic phenomenon, mitigating risk and ensuring safety and stability of the structure.

The Altair technology portfolio includes leading CFD tools that leverage both CPU-based Naiver-Stokes and GPU-based Lattice Boltzmann methods, allowing clients to select the best method to meet their challenges and project requirements.
