Getting Started
After installing Simcenter STAR-CCM+, you can access documentation and tutorials on the Support Center or within the installation.
- Context-Sensitive Search
  From within the Simcenter STAR-CCM+ interface, you can launch a combined search of the resources available in the Support Center and the online help. The resources include knowledge base articles and videos and submissions on Simcenter STAR-CCM+ Ideas.
- Accessing Help
  The Simcenter STAR-CCM+ documentation is provided in two formats, HTML and PDF. The PDF file can be found within the doc directory of your Simcenter STAR-CCM+ installation.
- Digital Product Experience
  To enable users to benefit from our personalized Digital Product Experience the collection of personalized data is necessary.
- Product Excellence Program
  Siemens Digital Industries Software collects information about the use of our offerings by its users. This information helps us to improve our product features and functionality to better meet our customers’ needs.
- General Simulation Process
  Simcenter STAR-CCM+ provides you with a simulation tool that allows you to test solution designs under virtual conditions. Although Simcenter STAR-CCM+ supports a wide range of modeling scenarios, there is a general workflow that you can follow in most situations.
- Simcenter STAR-CCM+ Licensing
  Simcenter STAR-CCM+ is licensed software that operates according to license feature keys that it checks out from the license management system. Apart from the default mode, you can launch Simcenter STAR-CCM+ in Read-only Mode, Lite, Power Session, and Power on Demand.
- Getting Support
  When you need assistance with using Simcenter STAR-CCM+, you can first check for resources on the Support Center.
- Suggesting Enhancements to Simcenter STAR-CCM+
  Siemens Digital Industries Software provides an area on the Simcenter STAR-CCM+ community forum where you can submit ideas for enhancing the software. The forum also allows you to comment on ideas from other users.
- Simcenter STAR-CCM+ Default Options
  The Options dialog is used to control a number of global options in Simcenter STAR-CCM+. The choices you make are stored in a properties folder that is unique for each version of Simcenter STAR-CCM+ you run on your machine.
- Controlling Graphics Performance
  Simcenter STAR-CCM+ offers various options for using graphics software and hardware for your simulation.
- Rendering Graphics Locally and Remotely
  By default, when you launch a Simcenter STAR-CCM+ server from a batch or interactive client on the same local machine, Simcenter STAR-CCM+ renders graphics in the client using the local graphics resources. Alternative rendering options are provided that provide better performance in different circumstances, including standalone rendering processes.
- Troubleshooting Graphics
  This section provides techniques for dealing with the following visualization problems:
  - Resolving Hardware Issues
    If you experience problems in displaying graphics within the Simcenter STAR-CCM+ Graphics window, install the latest driver for your graphics hardware. The process for obtaining and installing the latest driver depends on your graphics hardware. Refer to the manufacturer's instructions for details.
  - Working Without Graphics Hardware
    When hardware-accelerated drivers are not available on your machine, or when you must run Simcenter STAR-CCM+ remotely through an X-server (such as VNC), you can activate Mesa graphics libraries.
  - Mouse Pointer Positioning in 3D-CAD
    When using 3D-CAD on a virtual machine, you may experience an offset between the mouse position and your object selection. To resolve this issue, you can adjust the User Interface Scale.
  - A Scene Will Not Open
    If you are unable to open a scene, you can obtain information for troubleshooting.
  - Improving the Rendering of Concave Faces
    Some objects with highly non-planar polygons show artifacts. This problem is because Simcenter STAR-CCM+ attempts to triangulate these kinds of surfaces--a process that requires extra memory.
  - Z-Fighting Appears
    The model shows rear polygons “bleeding” from behind the front ones.
  - Limitations for High-DPI Displays
    Automatic scaling of UI elements on high-DPI displays (such as 4K) is not supported in the current release of Simcenter STAR-CCM+. If you wish to use such a display, use workarounds such as deactivating scaling to improve display quality of the user interface.
- Product Security
  Simcenter STAR-CCM+ is an analysis code that is designed to work within a secure network with trusted users.

A Scene Will Not Open

If you are unable to open a scene, you can obtain information for troubleshooting.

Right-click on the Scenes node and select Test Graphics.
Otherwise, right-click on the node of the particular scene and select Report.

Either command produces a report in the Output window containing technical details on the graphics hardware.

If the report ends with ***Report generated remotely***, graphics are being rendered on the server side of your simulation. For details, see Rendering Graphics on a Remote Server.

If you wish, simply send the information to support by selecting the text in the Output window, copying it and pasting it into an e-mail message.
