CHAPTER 2

Required Hardware & Software Configurations

2D Graphics Accelerators

Some systems offer optional 2D graphics accelerators to improve X11 performance.

SinceMSC.Patranisagraphicallyintensiveproduct,werecommendthatyouusea3D

graphics accelerator for optimum performance. MSC.Patran is only tested with the

graphics boards shown in the system specific tables.

Potential Color Flashing Problem

If MSC.Patranis running with otherX applications, the colors may flash if the mouse

is moved outside of an MSC.Patran window.

Though harmless, the flashing occurs if MSC.Patran tries to allocate colors in the

system’s default color map, when another X application has already allocated the

color map. MSC.Patran instead creates its own custom color map.

As long as the mouse is in an MSC.Patran window, MSC.Patran uses a custom color

map and the colors will be correct.

On HP systems, the color flashing problem may also occur if you define the

environment variable SB_X_SHARED_CMAP before you start the X Server.

(MSC.Patran does not require this variable.)

Additionally, the following parameter in the

settings.pcl file allows adjustment of

flashing problems.

pref_env_set_integer( “graphics_colors”, 120 )

Do not lower the number of colors below 64.

Display Resolution

MSC requires a minimum display resolution of 1024x768. A display resolution of

1152x864 or higher is recommended. For devices running at 1024x768, the

“SmallScreenLayout” preference must be set in the

settings.pcl file. See The

settings.pcl File (p. 102) for additional information.
