PRETECH uses e.g. the following software codes:

Creo Simulate (formerly Pro/MECHANICA)
Geometry element code for statics, vibration, thermal problems, kinematics, kinetics, fatigue; features: excellent optimization, control of numerical error due to p-method, direct access to databases of CAD-systems, fully parameterized and associated geometries, etc.
Fatigue calculation for Creo Simulate results; features: mean stress, local effects, temperature, surface roughness and treatment, etc.

Autodesk Simulation CFD©
Finite volume CFD-code for all cases of flow problems, e.g. laminar, turbulent, 2-phase, moving meshes and boundaries, thermal, radiation, etc.

ABAQUS™
Finite element code for statics, etc.; features: linear and nonlinear materials, large deflections, etc.

MARC/MENTAT™
Finite element code for statics, vibration, thermal problems, etc.; features: nonlinear materials, large deflections, contact with friction, radiation, etc.

Creo Parametric™
Feature based world leading 3D-CAD-System; features: volume models, parts, assemblies, integrated with Creo Simulate, interface to Autodesk Simulation CFD, MENTAT, etc.

FrameMaker™
Professional DTP-System; features: text, equations, tables, book functions.
