Fluid Dynamics Engineer


A Simulation Role for Engineers who perform routine fluid flow and thermal calculations to guide design modifications and explore innovative design concepts.

Note: All the capabilities offered in Fluid Mechanics Analyst Role (FLA) which was previously available before 2019xGA have been merged into Fluid Dynamics Engineer (FMK) role starting 2019xGA. The migration details are available in LPN.

Fluid Dynamics Engineer provides designers and design engineers with the ability to validate fluid and thermal performance for internal/ external flows and conjugate heat transfer problems. With a CAD-enabled CFD approach, Fluid Dynamics Engineer enables users to quickly explore 100s of designs while concurrently improving product performance based on optimal flow distribution, efficient thermal management, minimal pressure losses etc. Fluid Dynamics Engineer leverages industry-standard RANS based finite volume Computational Fluid Dynamics (CFD) technology with an integrated (CAD+CFD+PLM) and fully guided user experience tailored for Designers to perform end-to-end product design efficiently on a single collaborative environment of 3DEXPERIENCE Platform.

Fluid Dynamics Engineer benefits from Simulation Data Science capabilities enabling all simulation activities, models, and results to be linked, traced, updated, re-used, and analyzed with ease by all impacted users.

Fluid Dynamics Engineer (FMK) includes embedded compute licensing allowing routine execution of one concurrent simulation job on up to 8 cores.  The embedded computer is inseparable from its associated role. Access to embedded compute follows the same Named User or Concurrent license model as the role it is associated with.

Fluid Dynamics Engineer inherits the value of either of the following Platform Options as pre-requisites:

  • Simulation Foundation (SEI) provides apps and services that allow all users to access the corporate library of deployed simulation methods and benefit from a single location to find and monitor all of their simulation studies. See the Simulation Foundation or Multidisciplinary Optimization Engineer BFS documents for more information.

Multidisciplinary Optimization EngineerMDOMultidisciplinary Optimization EngineerAs a Role on the 3DEXPERIENCE Platform, Fluid Dynamics Engineer permits a seamless switch between applications, allowing users to be product-focused: applying the right tool at the right time in their workflow processes. This allows a much greater degree of flexibility and collaboration in the design and simulation process, where geometry changes are automatically updated and made immediately available on the same platform for the analyst to obtain updated results.

There are two key components to Fluid Dynamics Engineer which capture the CFD workflow processes: Fluid Model Creation and Fluid Scenario Creation.

  • Fluid Model Creation allows the user to easily build high-fidelity meshes for fluid flow calculations, which accurately capture boundary layers and automatically extract the fluid domain, thus reducing the need for most manual preparation.
  • Fluid Scenario Creation allows the user to define the fluid properties and the physics/boundary conditions that define the simulation scenario.

Fluid Dynamics Engineer benefits from the Simulation Data Science capability enabling all simulation activities, models, and results to be linked, traced, managed, updated, published, re-used, and analyzed with ease by all impacted users.

If used together, Fluid Dynamics Engineer (FMK) inherits all of the values of the Multidisciplinary Optimization Engineer (MDO) allowing the user to develop re-usable, deployable simulation processes, enabling simulation value to be experienced as an integral part of your product development activities.
