Overview

FAME is a simulation tool designed to model the laser powder bed fusion (LPBF) additive manufacturing process using the Finite Volume Method (FVM). This tool helps in understanding the thermal and mechanical behavior of materials during the LPBF process.

Features

• Thermal Simulation: Models the heat distribution and cooling rates.
• Mechanical Simulation: Analyzes stress and deformation.
• Material Properties: Supports various materials with customizable properties.
• User-Friendly Interface: Easy to set up and run simulations.

Installation

To install FAME you need to have anaconda installed then clone the repository and install the required dependencies:

git clone https://github.com/neoceph/FAME.git
cd FAME
conda env create -f environment_linux.yaml

Usage

To run a simulation, use the following command:

fame --input your_config_file.yaml

Replace your_config_file.yaml with your specific configuration file.

Configuration

The configuration file should include parameters such as:

• Laser power
• Scan speed
• Layer thickness
• Material properties
