In this tutorial, you will learn how to execute your first 3d topology optimization hello world program using top3d. This is your first step into the 3d topology optimization world!

In this tutorial, you will learn how to apply arbitrary loads in Top3d. Consider a unit cube with 8 nodes (Fig 1 on the left), each node has 3 degrees of freedom. Then the force vector F has the dimension…

In mechanical engineering, compliant mechanisms are flexible mechanisms that transfer an input force or displacement to another point through elastic body deformation. These are usually monolithic (single-piece) or jointless structures with certain advantages over the rigid-body, or jointed, mechanisms. In this…

Heat in physics is defined as energy transferred between a system and its surrounding. The direct microscopic exchange of kinetic energy of particles through the boundary between two systems is called diffusion or heat conduction. In this tutorial, you will…

If you want to make a topology optimization movie, simply follow this tutorial In some designs, some elements may be desired to be solid or void (active or passive). A matrix with ones at elements desired to be solid, and…

In this tutorial, you will learn how to use Matlab fminconfunction as an optimizer in our 3d topology optimization program. It constrains six(6) main steps, i.e., Initialize Fmincon, Define Objective function, Hessian, Constraint, Output function and Call fmincon. Hint: double…

In this tutorial, you will learn how to implement Method of Moving Asymptotes(MMA) to our efficient 3d topology optimization program (top3d) in Matlab. Updates: The parameter c_MMA is increased by a power of 10. The gradient of the mass…

The boundary conditions are defined in an evolutionary way in our top3d program. This tutorial will show you how to change boundary conditions effortlessly and effectively. The boundary conditions and loading conditions are defined in lines 12-18. Since the node…

In this tutorial, you will learn how to modify the original 3d topology optimization program(top3d) to solve multiple load cases problem. In order to solve a multiple load cases problem, as shown below, a few changes need to be made.…

In some designs, some elements may be desired to be solid or void (active or passive). In this tutorial you will learn how to set active and passive elements in the topology optimization program. In some designs, some elements may…
