Part 4: Apply boundary conditions to Chladni plate

Step 12: Constrain the Center Node of the Plate

•Double click the Plate_sim1 part in the Simulation File View pane using the left mouse button

•Select User Defined Constraint from the Constraint Type drop-down menu in the Loads and Conditions group of the Home tab tool ribbon

•Set all DOF fields to Fixed, except DOF3, which should be Free

•Select the node at the center of the plate

•Click OK

Step 13: Setup the Eigenvalue Extraction Parameters

•Right-click on the Subcase – Eigenvalue Method 1 and select Edit

•Click on the Create Modelling Object…     in the Lanczos Data row

•Set the Frequency Range -  Lower Limit to 0.1Hz

•Set the Number of Desired Modes to 40

•Click OK

Click OK
