Find Simulation Software Projects Easily

I need a specialist who can take one of our existing pieces of industrial machinery and retrofit it so it draws significantly less power while keeping—or ideally improving—its current output. The core objective is clear: increase overall efficiency by cutting energy consumption.

Your task starts with a thorough assessment of the present drive systems, motors, control panels, sensors, and power-management components. From there we will agree on the most practical upgrade route, whether that means installing high-efficiency motors and variable-frequency drives, redesigning control logic with PLCs, or incorporating real-time energy-monitoring hardware and software.

Key deliverables
• Diagnostic report outlining baseline energy use, points of loss, and recommended retrofits
• Bill of materials and sourcing list for all new parts or modules
• Implementation plan with step-by-step integration instructions and projected downtime
• On-site (or remote) installation support, tuning, and safety verification
• Post-retrofit performance data demonstrating the targeted reduction in kWh per production cycle

I already have basic schematics and operating manuals, and the machine is accessible for detailed inspection. Please highlight similar projects you have completed, the tools or platforms you prefer—such as Siemens or Allen-Bradley PLCs, energy-monitoring suites, CAD or simulation software—and your projected timeline to hit each milestone.

We need a developer to build a full-featured simulator on the CARLA open-source platform for practical driving training and human-factors research. The same codebase should support instructor-led training (urban, highway, off-road) and experimental modes for studying stress, drowsiness, and cognitive load on driving behavior. Both left-hand and right-hand driving configurations are required.

Core requirements:

Ready-made scenarios with dynamic actors (vehicles, pedestrians, cyclists) and weather/time variations, configurable via file or script.

Authentic vehicle dynamics (acceleration, braking, steering) using a preferred physics plug-in that integrates with CARLA's API.

Research hooks to trigger events (obstacles, reduced visibility, distractions) and log driver inputs, biometrics, and vehicle telemetry at millisecond precision, with a TCP/UDP or REST interface for external device sync (e.g., heart-rate, eye-tracking).

A user-friendly training dashboard with admin panel for scenario selection, objective setting, and performance metric review (speed, lane keeping, reaction time).

Deliverables:

Source code in a private Git repository with clear commit history.

A one-click installer or Docker image for Windows and Linux.

At least seven demo scenarios per driving context (urban, highway, off-road, hills, night, rain, peak traffic).

Documentation: setup guide, API reference, and sample research scripts.

A short video walkthrough proving dynamics fidelity and scenario switching.

Acceptance criteria:

Installer launches CARLA with all assets on a clean machine.

Speeds, accelerations, and steering angles match real vehicle data within ±5%.

Scenario reload takes greater and equal to 10 seconds without crashing.

Logged data streams have timestamp drift greater than 2 ms over a 30-minute session.

To apply: Share links to prior CARLA modifications, reinforcement-learning projects, or published human-factors work. All communication and work will remain on Upwork per platform policy. Do not share contact details in your proposal.

I'm launching a new website for my art and I'm looking for someone to create a premium 10–15 second looping hero animation for the homepage.

I create contemporary butterfly artwork, and I'm looking for a custom animation that reflects my brand. I have a reference video that captures the overall mood and quality I'm looking for. However, I do not want to copy it. Instead, I'd like you to create an original concept inspired by my artwork.


If this sounds like a project you'd be interested in, I'd love to hear your ideas, estimated timeline, and fixed-price quote.

Thank you, and I look forward to hearing from you.

Looking for a CGI / 3D video artist to create two premium, science-led simulations for Brillare / Root Deep.

The artist should be able to manage the full process from ideation, visual treatment, storyboarding, 3D simulation, animation, rendering, and final output.

Output 1: Water-in-Oil Microemulsion Technology
Create a luxury 3D simulation showing peptide molecules encapsulated inside oil droplets through microemulsion technology. The clips should explain how water-based actives are carried within oil droplets for better scalp-barrier compatibility and targeted follicle delivery.

Output 2: Follicle Science Ecosystem
Create a 3D simulation showing how Root Deep works on the follicle ecosystem through three actions: exfoliation and balance, stimulation and nourishment.

Visual Direction
The output should feel premium, clinical, luxurious, and science-led.
Use the brand palette of orange, ivory white, transparent gold, soft scalp tones, glass textures, clean reflections, and cinematic macro lighting.

Avoid anything cartoonish, overly medical, neon, cheap-looking, or generic biotech.

I need to hire a CAD designer with fabrication and materials experience. I am an acoustics specialist that designs large exhaust mufflers/silencers (e.g. 8m long by 4m diameter). Once the basic 3D design is done in my simulation software, I need a designer to complete the fabrication drawings. The ideal candidate should have experience in both design and fabrication processes because the CAD file you will be given wont have any thicknesses, attachment points, etc. You will need to work with me to specify these points so we have a set of drawings that can 1) actually be fabricated (i.e. there are no parts of the design that are physically impossible to make 2) the silencer wont fail (e.g. when moved it wont break under its own weight or wont fail due to the exhaust gas pressure inside, etc..).

Attached is a simple example showing what I would give you. I would of course be available for questions/clarification.

What I would want from you is a full drawings package I can just hand to my fabrication team.

Ideally I want to use AutoCAD, but open to your preference.

• What is your design software preference?
• What do you think are the design challenges of exhaust silencers?

I have a cyber-physical product in development and need a solid SysML model built in Cameo to capture the complete system architecture. My immediate priority is to map out the blocks, interfaces, and behaviors that govern how all electronic, mechanical, and embedded-software elements communicate with each other.

What I need from you
• A well-structured Cameo project file with package hierarchy, block definition, internal block, sequence, and activity diagrams that together describe the end-to-end architecture.
• Clear allocation of communication protocols across hardware and software components so it is obvious where messages originate, how they flow, and where they terminate.
• Sufficient stereotypes, constraints, and parametrics to make the model executable for future trade-off analysis.
• Brief model-based documentation (PDF or HTML) generated from Cameo, outlining assumptions and key design decisions.

Acceptance criteria
1. Cameo project opens without errors or missing profiles.
2. All physical blocks have ports typed with the correct protocol interfaces.
3. Every protocol interaction is represented in at least one sequence diagram linked back to the respective blocks.
4. Documentation automatically syncs with the model and reflects the latest state.

If you work daily with SysML v1.6 (MagicDraw/Cameo Systems Modeler) and have experience modeling communication layers in mixed hardware-software environments, I would love to see examples of your previous models or screenshots demonstrating clarity and consistency.
