Solving second order ODEs using MATLAB

ANSA file: https://drive.google.com/file/d/1rWoJVO91tcgRvbpWzmr7w1SQnlSAHDKM/view?usp=sharing Time Taken: 3 hrs 40 mins Procedure: Geometry clean up is done. Defeaturing is done throughtout the model. Note: In this model, there are many curved surfaces, so it will takes much time to do ortho tria in curved surfaces.…

PID…

Aim- Take the mid surface for all the components of the given Hood model and mesh the mid surface with the given element Quality criteria. Introduction- The hood or bonnet is the hinged cover over the engine of motor vechicles. Hoods can open to allow access to the engine compartment, or trunk for maintenance and…

Objective- Use the following 2D CAD drawings to create the 3D model of the internal Geneva mechanism (driver and driven wheels) Perform motion analysis by rotating the driver wheel at 10 rpm and 20 rpm. To plot the Contact force (between driving and the driven wheel) as a function of time for both cases.. To plot the Angular…

Objective- Create a 3D model of a flow bench Run a parametric study on different valve lift Run flow analysis and obtaining a plot a graph between lift and mass flow rate Introduction- A flowbench is a device used for testing the internal aerodynamic qualities of an engine component. It is mainly used for testing the intake…

Objective- Model the flow over a NACA0017 airfoil in Solidworks for the angle of attacks 0,2,4,6,8,10 compare the drag forces. Theory- The NACA airfoils are airfoil shapes for aircraft wings. The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical…

Theory- In this challenge we have to run a baseline simulation of a cylinder in which external flow takes place. And also calculate the Reynolds number. Then increase the Reynolds number by a factor of 20%, 40%, and 100% then run the transient flow simulation. Also create animations for pressure-velocity for all the three…

Objective- In this study, we will do the frequency analysis on the shaft contaning disc. There is most important to find the natural frequency because if the rotating shaft frequency matched with the natural frequency then a large amplitutde displacement will occured and shaft will distorted. So we will find the natural(critical)…

Objective- Your script should take column numbers as the input and plot the respective columns as separate images Each file should be saved by the name of the column You code should exit gracefully, if a non-compatible file is provided as an input. It should say something like \"File not recognized. Please provide a valid…

Objective-code to fit a linear and cubic polynomial for the Cp data pcov is a 2d array with the estimated covariance of the parameters in popt. It can be used to calculate the standard deviation errors of popt. np.array(temperature) is a grid of all temperature values, all of the same type, which basically stores values…

Objective- Reading \"NASA thermodynamic data\" file and write a function that extracts the 14 co-efficients and calculates the enthalpy, entropy and specific heats for all the species. Calculate the molecular weight of each species and display it in the command window. Plot the Cp, Enthalpy and Entropy for the local temperature…

Objective- To optimise the stalagmite function and find the global maxima of the function Expalin the concept of genetic algorithm in your own words and also explain the syntax for ga in MATLAB Plot graphs for all 3 studies and for F maximum vs no. of iterations MATLAB Code- clear all close all clc x = linspace(0,1,150);…

Objective- To simulate the transient behaviour of a simple pendulum create an animation of it's motion MATLAB Code- function [dtheta_dt] = ode_func(t,theta,b,g,l,m) theta1 = theta(1) theta2 = theta(2) dtheta1_dt = theta2; dtheta2_dt = -(b/m)*theta2 -(g/l)*sin(theta1); dtheta_dt = [dtheta1_dt; dtheta2_dt]; end b = 0.05;…
