While FDM technology of 3D printing can use traditional industrial plastics like ABS and Polycarbonate, resin 3D printers require special photopolymer resins that harden (cure) under UV light. Most 3D printing resins are either epoxy-based or acrylate-based, the latter used more often in desktop printers. Many thinks of resin 3D printed parts as fragile and […]
Read MoreWhen we want to add multiple step files of geometry in Ansys workbench, then in that case, follow the below steps: Open the design modeler. Go to the file option at the top. Then click on the import external geometry file option. At last, click on generate button. Repeat the same procedure for different step […]

Read MoreVarious reasons are responsible when the optimization algorithm’s convergence is not ensured. Some of the following steps are beneficial in fixing this issue: Ensure that the objective function and the constraints are appropriately formulated. Ensure that the objective and constraint functions are continuous and differentiable at least up to the second order. If the objective […]
Read MoreGradient vector: If the partial derivative of a function f(x) (function having $n$ variables) with respect to the $n$ variables $x_1$, $x_2$…..$x_n$ at a point $x^{\star}$ is taken, then that partial derivative vector of f(x) represents the “gradient vector” which is represented by symbols like $c$ or $\triangledown {f}$, as: $\mathbf{c}=\nabla f\left(\mathrm{x}^{*}\right)=\left[\begin{array}{c}\frac{\partial f\left(\mathrm{x}^{*}\right)}{\partial x_{1}} \\ \frac{\partial f\left(\mathrm{x}^{*}\right)}{\partial […]
Read MoreVarious types of uncertainties are considered in the topology optimization, like uncertainty in loading, geometry and material properties, etc. Two methods account for the uncertainties in the topology optimization framework. They are- 1. Probabilistic based methods (Statistical or reliability-based methods) 2. Non-probabilistic based methods The traditional approach to account for the uncertainties in the structure […]
Read MoreSelect 2D space dimension and select specific physics. Model some 2D geometry under Geometry 1 tab. Now, go to add component option under Home Tab and click on 3D. Right click on Geometry 2 and click on work plane. Work Plane 1 option now appears under Geometry 2 button and Plane Geometry option now appears […]
Read MoreNeed for explicit dynamic analysis Implicit and explicit are the two main types of time integration methods that are used to perform dynamic simulations. The explicit time integration is more efficient for the following situations- 1. To simulate the buckling and complex contact problem. 2. To model material deformation and failure at a high strain […]
Read MoreMetamaterials are those materials that are not found in nature and are artificially manufactured materials. The properties of such materials are derived from their internal microstructure (geometrical configuration) and not from their chemical composition. The concept of metamaterials was initially coined in the context of optics and electromagnetism. The properties of the metamaterials on the […]
