INTERNSHIP: CFD Multiphase Flow R&D

Role Description & Responsibilities

Our Dassault Systemes SIMULIA Fluid R&D is excited to announce we have a hybrid internship opportunity available in our Waltham, MA office!

As an intern within the physics research validation team, you will be responsible for verification, validation and facilitating development of novel fluid physics modeling methods in CFD for a broad range of applications related to aero-acoustics and multiphase flows. You will help the Team with the roll out of products and processes that simulate the world in which we live. We are the Dassault Systemes brand that provides simulation for product, nature, and life.

This is a paid sixth month internship/co-op, from June to December 2025. You will be working on a hybrid schedule in the Dassault Systèmes SIMULIA office located in Waltham, MA.

During this internship, you will assist with the physics validation of SIMULIA's flagship CFD solution on:

• Design, develop and continuously improve software in order to provide World Class Apps, Services &Technologies delivering experiences & value to end-users. Continuously improve deliveries based on usage & user feedbacks.
• Product release validations for all acoustics related workflows (T&M, A&D …) to ensure quality product release (accuracy, robustness & performance)
• Physics development validations (acoustics & multiphase) on numerical algorithms and fluid/acoustic modeling to further develop/expand product features in acoustics and multiphase capabilities for broader workflow coverage and enhancement in T&M, A&D ..
• Critical Customer project Investigations in acoustics/multiphase to identify gaps between current technology & workflows, and propose solution directions for product development.
• You’ll also need to perform literature review on selected topics and summarize findings, set up numerical tests for related CFD benchmarks, develop codes/scripts to automate
  
  

We are seeking a motivated and enthusiastic individual to join our team as a validation engineer on CFD multiphase flows with skills in the following areas:

• Problem-Solving Skills: Strong analytical and problem-solving skills to address challenges related to natural language understanding, dialog management, and user interaction.
• Communication Skills: Effective communication skills to collaborate with team members, gather requirements from stakeholders, and communicate technical concepts to non-technical audiences.
• Creativity: Ability to think creatively and explore innovative approaches to enhance the chatbot's capabilities and user experience.
• Self-Motivation and Learning Agility: Proactive attitude towards learning new technologies and methodologies, as well as the ability to work independently and adapt to evolving project requirement
  
  

Qualifications

PhD candidate in Physics, Mechanical Engineering, Aerospace Engineering or equivalent.

Academic background and strong interest in fluid dynamics or physics, with direct experience or specialization in aeroacoustics & multiphase flows.

Thorough understanding of CFD, Fluid Dynamics, Turbulence Modeling, aero-acoustics & multiphase flows, Experiences with CFD applications of

• Computational aeroacoustics for rotating machinery/gas turbines
• CFD multiphase gear lubrications are highly desired.
• Strong computer skills; familiarity with UNIX/Linux a plus. Experience with shell scripting and python programming is highly desired.
• Excellent problem-solving and organizational skills, Self-motivated individual with a strong work ethic, detail oriented, ability to handle multiple tasks/multiple projects simultaneously, able to work effectively in fast-paced team environment.
• Strong and effective English communication skills and good presentation skills.
• Rudimentary experience in geometry handling and preparation.
  
  

In addition to working with your direct team, as a member of Dassault Systemes NAM Intern Program you will be invited to our Speaker Series, Lunch and Learns, Networking Events and employee functions.

Besides the above, a sense of adventure and a willingness to have fun through work are great tools at our disposal. If you enjoy learning new things while working with a friendly group of highly skilled individuals, this could be a great fit for you!

This is an onsite role at our Dassault Systèmes Waltham, MA location; no remote or offsite permitted

Compensation for the role will be commensurate with experience. The total expected compensation range will be between $32 – $40 per hour.

We look forward to meeting with you and leaning why you feel you would make a great Dassault Systemes Intern.
