Initializing help system before first use

Notes for Insight users

Xpress Insight 4.11.2 or later is compatible with Mosel 5.

App models compiled with Mosel 4.2 or more recent can be run with Mosel 5. However, although they have been compiled with an older release, they will be executing on the new architecture and their behavior may change due to the refactoring of the array handling (see Section Array handling).

If you re-compile the App model with Mosel 5, be aware of the following:

  • All declarations of Insight entities need to be prefixed with the public qualifier (a quick workaround is to compile with the -g debug compilation option which preserves all global entities).
  • Insight 4.x does not support dynamic packages. Use the imports keyword instead of uses to statically link in packages.
  • Insight 4.x does not support the new namespaces feature.
  • Mosel 5 introduces some changes to the handling of arrays (see Section 'Array handling') which may impact your model. The symptom is that a previously (implictly) dynamic array is now dense and this is best diagnosed by asserting whether the size of arrays and/or their dependencies such as problem matrix dimensions are changed.

Note for Workbench users: Workbench now compiles BIM files into an output folder in the project, by default out, and copies the master BIM file into the root of the archive only on publish or download app. Therefore any legacy BIM file in the root of a project is obsolete and should be deleted to avoid confusion.
