Virtual Engineering

in the fields of decarbonisation, climate resilience, and sustainability

VIRTUAL ENGINEERING

refers to digital integrative and collaborative design and validation activities that enable continuous product optimisation in interdisciplinary and entrepreneurial partnerships. These can be implemented in early planning phases and, thus, support key decision-making processes in a transparent and auditable manner. Virtual Engineering accelerates the product or project development cycle, while simultaneously minimising the corresponding costs.

Combining the design-in-context capability of Virtual Engineering with product data management tools, like PLM or BIM, you get consistently correct assemblies and parts right from the start. No external data acquisition is required, avoiding the need for time-consuming and error-prone data transformations and integrations.

Virtual Engineering in the Built Environment Value Chain

Tools like Computational Fluid Dynamics (CFD) can be used to determine and optimise thermal and fluid dynamic conditions inside and outside buildings and their time-dependent behaviour in the field of building physics.

CFD offers both mean and sub-zonal as well as steady-state and time-resolved analysis capabilities. Simulation results are revisable and accessible at any time.

” CFD is an inherently data-driven tool and an integral part of the Digital Transformation in Architecture, Design & Planning.

Perceptive advantages and easy collaboration

The perceptive advantages of CFD and FEA well exceed those of other software tools. In our solutions, we incorporate simulation results into Augmented and Virtual Reality visualisation solutions. This provides immersive experiences: Already in early planning phases, your object will become accessible – or you can literally immerse yourself in the interior of your product during its operation. This is often not possible with a physical prototype.

Such new methods and visualisation solutions also enable completely transparent and interdisciplinary planning processes with the direct involvement of all stakeholders – regardless of where they are located. Virtual Engineering thus lifts planning, collaboration and participation to a new level.

We develop streamlining solutions for typical workflows in virtual product development that are specially tailored to your requirements. CFD and FEA simulation are integrated as digital modules into your design process via APIs, with all scaling advantages of the cloud.

Efficient virtual product development

Accurate physical simulation of the design and function of a product, its manufacturing and subsequent application saves both time and costs in the multi-faceted process of product development.

Extensive functional and stress tests can be performed on virtual prototypes well before the production of the first technical prototypes starts, allowing the designer and engineer to immediately assess their designs’ suitability.

Accelerate your workflows with parameterisation, automated optimisation and Co-Simulation

CFD and FEA provide capabilities for parametric design and automation of certain planning processes. Proven performance metrics can be determined and monitored during simulation. This shortens and simplifies many feedback cycles of the design process.

In addition, the scientific and technical analysis processes built into simulation tools enable optimisation of your designs according to requirements. These optimisation processes can be performed manually or fully automated.

Co-Simulation goes one step further and simplifies workflows: it integrates customised simulation tools directly into your workflows and tools – either via software integration (plug in) or API. In this way, analysed simulation results are immediately available in your well-known and trusted design environment. This offers the greatest possible flexibility in the design of your digital work and development processes. Moreover, the effort required to integrate the complex world of physico-chemical simulation is considerably reduced. Additional investments in specialised hardware and expert knowledge are not necessary.
