GUI Basic Tutorial Step 10
Step 10: Defining Boundary Conditions
Let us assume that we need to define one material type for the entire
mesh, and a single node-based boundary condition on all surfaces. This
is accomplished by identifying an Element
Block and a Nodeset,
respectively; the id numbers assigned to these entities are assigned by
the user, usually by some convention meaningful to the analysis to be
done. The element block and nodeset are identified from the Materials
and Properties button on the control panel.
- Select the Analysis Groups and
Materials button and then Blocks in
the Control Panel window
- Select the Create button
- Select Create block in
the pull down menu
- Enter 100 into the Block ID field
- Select the Volume radio button
- Enter the id of Volume 1 by selecting it in the
graphics window, or just manually entering in ID(s)
field
- Press Apply
