compas_fea2

2nd generation of compas_fea. Current main changes:

Plug-in architecture
Improved API for in-parallel development
Extended functionalities

Package Objectives

This package aims to create a bridge between the generation of structural geometries and their analysis using popular commercial FEA software. The geometry generation features of these software are usually limited, tedious, and time-consuming.

Users

Simplify finite element analysis with 'pre-made' recipes to help inexperienced users get meaningful results
Better link with compas and its ecosystem
Provide a unified (as much as possible) approach across multiple backends to help researchers communicate with their industrial partners. For example, a researcher develops a structural system for a pavilion using Abaqus, but the engineer of record uses Sofistik to check the results: the analysis model for both structures can be derived from the same script with few changes
Increase the number of backend solvers supported

Developers

Clearly separate frontend (geometry generation, problem definition, and result displaying) and backend (FEA analysis, result post-process) to enhance in-parallel development
Offer frontend and backend developers a framework to help the structuring of their modules and avoid code repetition
Provide comprehensive documentation and examples to facilitate the development and integration of new features
Ensure modularity and extensibility to allow easy addition of new functionalities and support for additional FEA software

Installation

To install compas_fea2, use the following command:

bash pip install compas_fea2

Usage

Here is a basic example of how to use compas_fea2:

```python

Import the compas_fea2 library

import compasfea2 from compasfea2.model import Model, Part, Node, Element, Material, Section from compas_fea2.problem import Problem, Step, BoundaryCondition, Pattern, Load, FieldOutput

Define a Model and its parts

mdl = Model() prt1 = Part() prt2 = Part()

Assign the parts to the model

mdl.addparts([prt1, prt_2])

Define sections and materials

mat = Material(E=..., v=..., density=...) sec = Section(t=..., material=mat)

Define the geometry of the structure

Specify nodes

nodes1 = [Node(xyz=...), Node(xyz=...), ...] nodes2 = [Node(xyz=...), Node(xyz=...), ...]

Assign the nodes to a part

prt1.addnodes(nodes1) prt2.addnodes(nodes2)

Specify elements

elements1 = [Element(nodes=[...], section=sec), Element(nodes=[...], section=sec), ...] elements2 = [Element(nodes=[...], section=sec), Element(nodes=[...], section=sec), ...]

Assign the elements to a part

prt1.addelements(elements1) prt2.addelements(elements2)

Define boundary conditions

Apply constraints and loads to the structure

bcs = [BoundaryCondition(nodes=[...], ...), BoundaryCondition(nodes=[...], ...)] mdl.add_bcs(bcs)

Define a Problem to analyze

prb = Problem()

Add the problem to the model

mdl.add_problem(prb)

Define the steps of the analysis

stp1 = Step(...) stp2 = Step(...)

Add the steps to the problem (note: this is the sequence in which they are applied)

prb.addsteps([stp1, stp_2])

Define the load patterns

pattern1 = Pattern(nodes=[...], load=Load(...)) pattern2 = Pattern(nodes=[...], load=Load(...))

Add the pattern to the step

stp1.addpattern(pattern1) stp2.addpattern(pattern2)

Define the outputs to save

output = FieldOutput(...) stp1.addoutput(output) stp2.addoutput(output)

Run the analysis

Execute the finite element analysis

prb.analyzeandextract(...)

Post-process the results

Extract and visualize the results

results = prb.results

View the results

prb.show() ```
