AC3D Modeller


# 1: Introduction

AC3D is a popular 3D object/scene modeller available for Linux, Windows 95/NT, and SGI. It is very easy to use but powerful too - anyone can create good looking 3d objects in minutes.

# 2: Examples

Some models built with AC3D (VRML files)

stadium (37kW) plane(15k)

Someone's desk... (37k) Car(13k) 

Webpages are available that show off some models that AC3D users have built - some of the models are downloadable.

The aeroplane example shown above was downloaded from the internet and loaded into AC3D:

A PHOENICS dat file was exported, and used as the geometry for an object:

Inlet and outlet boundary conditions were added, and the solution of velocities and pressure was turned on, together with the KECHEN turbulence model. The solution produced the following pictures:

Pressure on the centre-line and body surface.

Streamlines starting on circles upstream of the plane.

Closer study of the solution showed that the wings generate negative lift, because of the peculiar cross-section chosen by the anonymous creator.
