The objective of this tutorial is to show how to use the Multi-Domain technique.
The model used is a low speed pole impact on a bumper system. Note that the model is
finely meshed (average mesh size = 2mm) in the region of the pole impact and
coarsely meshed (average mesh size = 10mm) elsewhere. Figure 1.
In order to run this analysis using Multi-Domain technique, you have to split this
model into two domains, one containing the finely meshed region and the other
containing the rest. A node to node link (/LINK/TYPE4) is then
specified at the boundary between the two domains.
These domains will be created using a pre-processor (using HyperCrash in this tutorial) and the options specific to
Multi-Domain analysis will be added to the input decks through a text editor. A
Multi-Domain main input file will also be created using a text editor.
