digitalmodel 0.0.8

engineering asset digital model(s) for life cycle analysis

Introduction

Sustainable Digital models for engineering assets built with sustainable engineering processes and solutions. The objective of digital models is to utilize a single source of ascii inputs (promoting single source of truth) to generate equivalent analytical models to encompass lifecycle operations of a product.

These operations include (and not limited to) the following:

• Analytical calculations
• Computational analysis
• 3D CAD models
  • 3D animations
  • Drawing automation

Dedicated to my idol and a lifelong chief engineer, Mark Cerkovnik. His insights shaped major portions of my life and this repository.

Summary

• High level vision proposed:

The library is intended to get traction from stretched engineering teams. Teams using this can take away some good ideas generated from leading/mentoring over 200 SURF engineers over 20 years of hands-on engineering experience. The main objectives of the library are:

• Single ascii data source of truth: generate fe models, analytical calculations, 3d cad models, 3d animations, drawings using a single source of truth
• Modularity : engineering assets can be imported into sofware using .yml files
• Standardize naming conventions: for cross-team/company collaboration
• Reusability of components: do once, use many times
• Analytical QA: If certain tasks can be done analytically, verify the outputs from analytical calculations vs. Orcaflex outputs. eg: Weights of components expected vs. model
• A major impact will be in the QA of the work for the end users as well as the responsible leads.
• Avoid excel to eliminate manual steps. Helps in automation of tasks and no/less room for error.

Usage

Using the Repository:

• The repository is intended to be used as a library for engineering assets. The library is intended to be used by engineers to generate analytical models, computational models, 3D CAD models, 3D animations, and drawings.
• The repository is organized in following key folders:
  • docs: Contains the documentation for the library
  • src: Contains the source code for the library
  • src/tests: Contains the test cases for the library

A quick way to running code is: - Create a virtual environment: - Use conda yaml file to create a new environment - (or) by installing digitalmodel package in an environment

• Run the following batch files
  • Download this digitalmodel repository
  • activate environment
  • Change command line to "digitalmodel" (outside not in src) folder
    • Run the following python files in tests:
      • python src\digitalmodel\tests\ {change_to_relevant}.py
      • i.e. for catenary riser, python src\digitalmodel\tests\test_catenary_riser.py
    • (or) Run the following batch files in tests:
      • python src\digitalmodel\tests\ {change_to_relevant}.bat
      • i.e. for catenary riser, python src\digitalmodel\tests\test_catenary_riser.bat
