Tutorial Autodesk CFD Pemula

Introduction

This tutorial provides a step-by-step guide for beginners on how to perform pipe pressure analysis using Autodesk Simulation CFD. Autodesk Simulation CFD is a powerful tool for simulating fluid flow and heat transfer, making it essential for engineers and designers. This guide will help you get started with the software and understand the basic processes involved in conducting CFD analysis.

Step 1: Download and Install Autodesk Simulation CFD

• Visit the Autodesk Education website at Autodesk Simulation CFD.
• Create an account or log in if you already have one.
• Select the appropriate version for your operating system and download the software.
• Follow the installation instructions provided on the website to complete the setup.

Step 2: Create a New Project

• Open Autodesk Simulation CFD.
• Click on “New Project” to start a fresh analysis.
• Choose a suitable template for your pipe pressure analysis. Check the available templates and select one that fits your needs.

Step 3: Import or Create Geometry

• If you already have a 3D model of the pipe, import it:
  • Go to the "File" menu and select "Import."
  • Choose your 3D model file (commonly in formats like .STL or .IGS).
• If you need to create the geometry:
  • Use the built-in design tools to draw the pipe system.
  • Ensure to define the correct dimensions and features of the pipe.

Step 4: Define Fluid Properties

• Click on the "Fluids" tab to set the properties of the working fluid (e.g., water, air).
• Specify the following:
  • Density
  • Viscosity
  • Temperature (if relevant)
• Make sure to select properties that reflect the conditions of your analysis.

Step 5: Set Boundary Conditions

• Navigate to the "Boundary Conditions" section.
• Define the inlet and outlet conditions:
  • Inlet: Specify the velocity or pressure at which fluid enters the pipe.
  • Outlet: Set the pressure or flow conditions at the exit point.
• Consider adding wall conditions to represent the physical boundaries of your model.

Step 6: Generate the Mesh

• Click on the "Mesh" option to create a computational grid for your model.
• Adjust the mesh settings:
  • Select the level of detail (more elements for more accuracy, but increased computation time).
• Generate the mesh and review it for any errors or issues.

Step 7: Run the Simulation

• Once everything is set up, proceed to run the simulation:
  • Click on the "Run" button in the toolbar.
  • Monitor the simulation progress and check for any errors that may arise.
• Adjust parameters if necessary and re-run the simulation to refine your results.

Step 8: Analyze Results

• After the simulation completes, go to the "Results" section.
• Use the visualization tools to:
  • View pressure distribution along the pipe.
  • Analyze flow patterns and identify areas of interest.
• Take note of critical points where flow might be problematic or where pressure drops significantly.
