Describe the Simulation

The simulation setup runs through the Dr.Q chat interface, which asks for each parameter step by step. Once verified, the boundary conditions and loads are visualised directly on the 3D model.

Step 1 — Assign a material

Every component needs material values so the solver can calculate its behaviour:

• Young's modulus (E) — stiffness of the material
• Poisson's ratio (ν) — lateral contraction under load
• Density (ρ) — required for self-weight and dynamic analyses

The platform provides a database of common materials to choose from.

Step 2 — Define boundary conditions

Specify how the component is supported:

• Fixed constraint — all degrees of freedom locked (e.g. bolted flange)
• Restricted displacement — movement allowed in specific directions only
• Symmetry — use when model and loading are symmetric to halve computation time

The model must be neither free-floating nor over-constrained.

Step 3 — Apply loads

Define the external influences acting on the component:

• Forces — concentrated or distributed
• Pressures — load per unit area, normal to a surface
• Gravity — self-weight of the part
• Thermal loads — temperature-induced expansion

Start with the simplest relevant load case.
