Mobile Multibody Dynamics

The first multibody dynamics app for iOS and Android

“MOMDYN” is a high-performance physics engine designed for real-time multibody dynamics and kinematic analysis on mobile platforms. Built to bridge the gap between desktop-class simulation and on-the-go engineering, the app enables complex system modeling using customized symbolic math and numerical integration routines built in Python with SymPy Mechanics. It serves as a portable lab for mechanical and aerospace engineers to validate motion physics, joint constraints, and system responses without the need for a workstation.

YouKon

Precision Unit Conversion & Property Database

A cross-platform engineering utility designed to move beyond simple unit conversion into structured project management. Built using Kotlin Multiplatform (KMP), YouKon allows engineers to build and maintain comprehensive databases of physical properties, organized by specific projects rather than isolated calculations. By integrating Firebase for secure cloud synchronization, the app ensures that technical data is persistent and accessible across devices. As an Open Source project, it demonstrates a commitment to transparent, high-quality software architecture, featuring a shared business logic core that powers a unified experience for both iOS and Android users.

AR Mobile Robotics

AR Digital Twins & Spatial Robotics Simulation

A professional-grade spatial computing platform designed for the visualization and real-time simulation of robotic systems. ARMOR (AR Mobile Robotics) leverages RealityKit to transform static URDF files into interactive Digital Twins within an augmented reality environment. By integrating high-fidelity physics engines like MuJoCo, ARMOR allows engineers to validate kinematic chains within an industry standard simulation environment. It is a specialized tool for the modern robotics workflow, bridging the gap between theoretical XML parsing and physical spatial awareness.

About Us

Engineering the Interface of Physics, Engineering and Software

At DC Engineer, we bridge the gap between traditional Aerospace and Mechanical Engineering and the frontier of Spatial Computing. Our technical lead brings 15 years of experience in dynamics and motion physics as a staff supervisor at world-class national research laboratories. We specialize in developing custom software solutions that require a deep understanding of the physical world.

Our portfolio spans from open-source engineering utilities to AR-driven Digital Twins for complex robotics and medical devices. Whether we are porting high-performance physics algorithms to mobile via SwiftUI or Kotlin Multiplatform or architecting MuJoCo-integrated simulations in AR, our goal is to provide ‘engineering-grade’ precision on every platform.

Our Core Offerings

Custom Software Development: High-performance mobile and desktop applications tailored for engineering workflows.

Spatial Robotics & Digital Twins: Transforming URDF and CAD data into interactive AR/VR environments for validation and training.

Technical Consulting: Expert-level guidance on dynamics, simulation modeling (MATLAB/Simulink/Abaqus), and real-time kinematic software architecture.

Mechanical

Eliott Radcliffe has 15 years of experience as an aerospace and mechanical engineer, specialized in dynamics, the physics of motion. He is skilled in numerical analysis, simulation modeling, finite element analysis, hardware design, and testing, and is an expert user in software including MATLAB, Simulink, Simscape, and Abaqus.

Mobile & 3D

The mobile ecosystem is vast, with exceptional apps crossing over a diverse set of use cases. One area that is notably absent, however, are applications that provide real-world utility to mechanical engineers. Our vision is to create our own suite of software that is accessible and budget-friendly that enable scientists, engineers, and other technically-inclined folks to harness their creativity while on-the-go.
