Calculate technical fundamentals right where they're needed

Many engineering tasks do not begin with a complex design, but with simple questions:

What stresses are generated? What geometric values do I need? How does a component change with temperature? Which tolerance chain is critical? The basic modules provide quick answers and complement the specialized MDESIGN calculations.

Establish standards, accelerate engineering

MDESIGN provides a consistent basis for calculations across the entire team. Structured data entry, centrally maintained calculation bases, and consistent documentation ensure that results remain traceable and comparable across projects.

For over 40 years, MDESIGN has been helping companies calculate and design technical components—today with more than 35,000 users worldwide.

Module Overview

Core modules bundled in one compact package

Numerous specialized modules are available for standard and basic tasks. They assist with quick preliminary calculations, technical plausibility checks, and recurring engineering problems.

Basics

Quickly determine technical indicators

The basic modules provide essential values for sizing, design, and verification—such as forces, stresses, movements, cross-section values, tolerances, pressures, or geometric parameters.

Physics

Calculate mechanical, hydrostatic, and dynamic relationships: forces, motion, vibrations, strains, buoyancy, and moments of inertia.

15 modules
Mechanics of deformable bodies Hydrostatics and hydrodynamics Kinematics Dynamics Gravity Rotational motion of rigid bodies Damped mechanical oscillations Superposition of mechanical oscillations Free, undamped mechanical oscillation Strain calculation Moments of inertia Moment of inertia of a plane Axial moments of inertia Axial moments of area Bearing force, buoyancy in liquids

Geometry

Determine geometric parameters for 2D and 3D objects: surfaces, volumes, triangles, cross-sections, and length divisions.

5 modules
Geometric data (2D) Geometric data (3D) Triangle calculation Cross-section properties Division of lengths

Dynamics & technical mechanics

Evaluate loads and performance parameters of technical systems: Shafts, ropes, hoists, inclined planes, bars, torque, and power.

6 modules
Torsional stress in a shaft Dynamic stress in a rope Forces on hoists Mechanical power during rotational motion Inclined plane Stresses in a rod under impact loading

Strength, contact & tolerances

Check stresses, compressions, and dimensional deviations: comparative stress, Hertzian compression, fits, tolerances, thermal expansion, and efficiency.

11 modules
Comparative pressure Hertzian pressure Hardness values Stress concentration General tolerance Thermal expansion ISO Fitting System Tolerance Analysis Pressure between bodies Efficiency Surface pressure

Shells, pipes & bodies

Analyze simple component and pressure stresses: cylindrical, conical, spherical, and rotationally symmetric solids, as well as tubes and assemblies.

12 modules
Cylindrical bowl Conical bowl Spherical shell Rotationally symmetric shell Torus shell, membrane stresses, and deformations Tube Spherical shell, cutout Long conical shell Cylindrical shell with ends Torus shell, bending and membrane stresses Units Additional shell and solid calculations
Why Foundational Modules?
