An oil pan which is constrained in all directions on the bolting locations and normal mode
analysis is performed. Topology optimization with the MAXW updated in the
design variable (DTPG) card to control the maximum bead width in the
optimization.
Objective
Maximize the first normal mode frequency
Constrains
Maintain the beadfrac response within the range 0.5 to 0.8
Design Variables
Topography
