3. Introduction to Ansys Ansys workbench serves as a comprehensive simulation environment, amalgamation diverse engineering simulation tools into a unified platform. With its user friendly interface, it enables engineers and designers to perform complex simulations across various disciplines such as Structural, thermal, fluid dynamics and electromagnetics. By facilitating seamless workflow integration and robust simulation capabilities, Ansys workbench empowers users to analyze, validate and optimize designs efficiently, Its intuitive features allow for iterative analysis, aiding in the creation of innovative and reliable products while reducing development time and costs.

4. Role in the Chemical engineering Reaction Engineering - Ansys facilitates the modeling and simulation of complex chemical reactions within reactors and other chemical processing units. Thermal Analysis - For process involving heat transfer, thermal management or thermal stress, Ansys workbench enables thermal analysis. Fluid Dynamics – It aids in simulating fluid flow behavior, pressure drops, mixing processes and multiphase flows. Multiphysics simulation – it allows engineers to couple different physics phenomena (such as fluid, heat transfer and chemical reactions) in a single simulation. Material and Structural analysis – For chemical equipments subjected to mechanical stresses or corrosive environments, Ansys can perform structural analysis helping in material selection, durability assessment and failure prediction Optimization and Design – Engineers use Ansys Workbench for design optimization, ensuring efficient performance and cost effective designs of chemical processes and equipment.

5. Industrial product cycle

6. Ways to solve any engineering problem Analytical Method Classical approach 100% accurate Applied on simple problems Numerical method Mathematical representation Approximation and assumptions are made Applicable even is physical prototype not available. Experimental method Actual measurement Time consuming Applicable only if physical prototype available (multiple prototypes are tested).

7. Different Numerical Techniques FEM(finite element method) FVM(finite volume method) FDM( finite difference method) BEM (boundary element method)

8. Finite element Method (FEM) Tension

9. Boundary Element Method(BEM) Just like the finite element method, it also requires nodes and elements, but as the name suggests it only considers the outer boundary of the domain. So, when the problem is of volume, only the outer surfaces are considered. If the domain is of an area, then only the outer periphery is considered. This way it reduces the dimensionality of the problem by a degree of one and thus solving the problem faster.

10. Finite Difference Method(FDM) In general, the finite difference method is described as a way to solve differential equation. It uses Taylor’s series to convert a differential equation to an algebraic equation. In the conversion process, higher order terms are neglected. It is used in combination with BEM or FEM to solve thermal and CFD coupled problems. This method is mainly used in the areas where the Fluid is involved. In below Figures, we can see the lung capacity being simulated using FDM.

11. Finite Volume Method(FVM) This particular method is generally used to solve a number of CFD problems (problems related to fluid flow). It is the most popular method to solve Fluid related problems. The values are calculated at discrete volumes on a generic geometry. The unit volumes are considered in FVM like that of finite elements that are considered in FEM. Variables properties include Pressure, velocity, area, mass…etc.

12. Degree of freedom (DOF ) The minimum no of parameters (motion, coordinates, temperatures, etc.) required to define the position and state of any entity completely in space is known as degree of freedom (D.O.F). Total DOFs of a meshed model = DOFs for each node * No of nodes Nodes and Elements In FEA, we divide a model into small pieces. Those are called Finite Elements (FE). Those Elements connect all characteristics points (called nodes) that lie on their circumference. This “connection” is a set of equations called shape functions. Each FE has its own set of shape functions that connect all of the Nodes of the Elements. Adjacent Elements share common Nodes (the one on the shared edge). This means that Shape Functions of all the Elements in the model are “tied” thanks to those common nodes.

13. Boundary Conditions The Boundary condition is the application of load and/or constraint. Using Boundary conditions we try to simulate the environment where the body will stay or function. Loading Condition Constraint
