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
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
