Functionality
STAR-CCM+ is a powerful finite-volume-based program package for modelling of fluid flow problems. The name STAR stands for "Simulation of Turbulent flow in Arbitrary Regions". It is maintained/developed by Siemens PLM Software (formerly CD-adapco Group). The STAR-CCM+ package can be applied to a wide range of problems such as
- Aerospace Engineering
- Turbomachinery
- Chemical Process Engineering
- Automotive Engineering
- Building and Environment Engineering
Conditions for Usage and Licensing
| Info |
|---|
To use STAR-CCM+ you need to mail support@nhr.zib.de and ask to become a member of the UNIX group adapco. |
You can check your group membership by calling groups.
| Info |
|---|
Within the core-h limits of Test Projects (see test account) we provide free Power On Demand (POD) keys for teaching/academic research of non-industry funded projects. |
In order to run STAR-CCM+ you have to specify the parameters -licpath and -podkey, as shown in the example scripts below.
Introduction and courses
A product overview is provided here. This documentation describes only the specifics of installation and usage at NHR@ZIB systems. Introductory courses for STAR-CCM+ as well as courses for special topics are offered by Siemens PLM Software: as a student you can join the Siemens Xcelerator Academy for Academics for free.
Documentation and materials
STAR-CCM+ products come with complete documentation. The User Guide is available in PDF format, see directory /sw/eng/starccm/<version>/STAR-CCM+<version>/doc.

Known Issues
To check if the license server of CD-adapco is accessible type:
telnet flex.cd-adapco.com 1999
This test (Trying ...) is positiv if the server answers (within a second):
Escape character is '^]'
Typically, after some minutes, a negative test outcome is indicated by:
telnet ... Connection timed out
