modelworldModel
Extends from PDE.Icons.BlockIcon.
Information
The worldModel block provides information that are propagated to other blocks. If for example the user
change the number of grid points, n, this change will propagate to all blocks in the model that need this
information.
Other information that are propagated are listed in the table below. It is for example also possible to
to chose the order of the derivation.
