Description: Topology Optimization of a Solid Aluminum Plate with an Objective Function to Increase the first natural frequency
Product/Topic Name : Altair Optistruct 2023.1
Comments: Please provide a solution on what would be the design constraints, Optimization Responses, Objective Function and Design Variable. My goal is to optimize the first natural frequency AND get an optimized shape with element densities highlighting the areas which need to be stiffened/essential to maintain the durability of the component.
Mesh Type: 2nd Order Solid Tetrahedral Elements
Here is what my Optimization cards are:
Design Constraints:
DCONSTR, Response: Volume Frac, Lower Options: OFF, Upper Options, Upper Bound: 0.4
Design Responses:
DRESP1 VOLFRAC, Response Type: volumefrac, Property Type: Total
DRESP1 FREQ, Response Type: frequency, Mode Number: 1
Objective Function:
DESOBJ(MAX), Maximize, Response Id: DRESP FREQ, Loadstep Id: Modal_Analysis (Normal Modes)
