NAFEMS conference (2021) - Reliable Meshing of 10 000 Parts


1. recursive car (2019)

A 1:20 copy of the car (= toy car) is inside the car, and a 1:20 copy of the toy car ...

These displacements were calculated requiring RESULOTION 20.0 globally and RESOLUTION 2.0 locally for the front brake parts. The mesh is intentionally coarse to demonstrate that physics already work in this stage. Making this mesh is descibed in User's Guide - DPT Bike.






3. disc brake assembly (2021, MARC)





3.0 heat transfer, thermal expansion

the loss of a car's kinetic energy defines the thermal load of the disc brake.
initial velocity = 150 km/h, deceleration 10 m/sec**2, mass = 1500 kg

tetras 228987
average quality 0.306
% quality < 0.05 3.68
worst tetra 4.61e-5




3.1 Eigenforms of the disc brake









3.2 Repeated braking

0-4.. sec deceleration from 150 km/h to 0 km/h
4-40. sec stop and acceleration to 150 km/h
40-44 sec deceleration from 150 km/h to 0 km/h
44-80 sec stop and acceleration to 150 km/h








3.3 Imprints are the common faces between parts
