2NEW SOFTWARE BUNDLES
The functionality of COSMOSWorks2005 depends on
which software bundle is used. In this book we
cover the functionality of COSMOSWorks
Professional 2005.

8INDEPENDENT MESH FOR EACH STUDY
In earlier releases of COSMOSWorks, studies
shared one mesh represented by the Mesh icon in
the tree. When you run a study, the program uses
the active common mesh. In this release, each
study that requires a mesh, has its own mesh. A
Mesh icon appears in the tree for every study
that requires a mesh. You can copy a mesh from
one study to another compatible study.
