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

Create a nodeset by following the steps below

Open the Nodeset window on the Control Panel
Select the Create button
Enter a Nodeset id of 100
Select the Surface radio button and type all in the ID(s) field
Press Apply
