How to create custom parametric structures with Open and flexible API?

To create custom parametric structures with an Open and flexible API, you need knowledge in parametric modeling and visual programming. Parametric modeling shapes 3D models based on parameters, while visual programming uses graphical elements for scripting.

OpenBuildings Designer by Bentley Systems is one software supporting this approach. It’s a BIM software that allows customization through various programming languages and tools, with Grasshopper being one of them.

Here are the basic steps to create custom parametric structures:

1. Create a 2D parametric sketch.

3. Create a 3D parametric element using the 2D profile.
4. Modify the 3D element using handles or parameter changes.
5. Apply constraints to the 3D elements.
6. Apply variable-driven features to create complex design components

What are the differences between implicit and explicit methods for multibody dynamics?

Implicit and explicit methods in multibody dynamics differ in how they solve differential-algebraic equations (DAEs) that describe motion and constraints.

Implicit Methods:

• Solve both current and next states simultaneously.
• A-stable (unconditionally stable for any time step).
• Suitable for stiff problems and nonlinearities.
• Examples: backward Euler, implicit Runge-Kutta, HHT method.

Explicit Methods:

• Depend only on the current state.
• Not A-stable (conditionally stable within a limited time step range).
• Less suitable for stiff problems and nonlinearities.
• Examples: central difference, explicit Runge-Kutta.

Choose the method based on your specific needs and system characteristics.

Challenges and limitations of using software for structural analysis

Using structural analysis software has advantages, including improving design efficiency, accuracy, and quality, enabling collaboration, and allowing for diverse simulations. However, challenges and limitations can arise, such as:

1. Sources of Error:

Software may yield incorrect results due to factors like numerical inaccuracies, poor model selection, discretization issues, software limitations, human input errors, and more. Verification with theoretical or experimental data and quality control are crucial to ensure reliable outcomes.

2. Learning Curve:

Complex or specialized software may have steep learning curves, requiring time and effort for effective use. Training and guidance from experts or online communities are often necessary. Choosing software that suits your needs and seeking resources for learning are essential.

3. Cost:

Structural analysis software can be expensive, with various pricing models, including one-time payments, subscriptions, and maintenance fees. It’s important to assess software based on your budget and goals to find a cost-effective solution.

4. Compatibility:

Some software may have compatibility issues with other tools used in the design process. Importing/exporting data in standardized formats and integrating with parametric modeling, visual programming, or fluid analysis tools can be challenging. Using software with open and flexible APIs and appropriate plugins can enhance interoperability
