LibAster Structural and Thermomechanical analysis in Python

Based on CodeAster, LibAster is an Open Source Python-library for structural and thermomechanical analysis. Using Python, it should be quite portable between platforms.

While this is not as user-friendly to get started, e.g. when comparing with full Desktop applications, having a library or command line tool makes it easier to connect into a workflow.

Right now, I would like to reach a point where I can launch energy, cost and structural analysis from BIM models, where, in addition, the generation of the BIM model would be generated parametrically. Translated into software names, this could mean something like steering a design from Grasshopper, transferring it into ArchiCAD or Revit or (preferably) IFC and launching different analysis calculations in parallel from there.

    Hi, may you share some code?
    would be nice to see that in action...

    I am only learning the stuff. Thus far, I have not been able to compile LibAster on my Mac. Python is there and after installing gfortran and hdf5, I can get about 80% of the modules to compile, but now another compilation problem arises.

    Hi,

    you can post your problem on the mailing list (http://www.python-science.org/mailinglist/2348).

    You can also take a look at the forge and download the source code:

Improve usage of BIM during early design phases

When I was collecting ideas for a book chapter on BIM (that seemed to never have emerged after that), I collected 10 ideas, which I believe still reflect good recommendations to improve the usage of BIM during the early design phases. These ideas are related to BIM software, but you can apply them in any flavor, as long as you can model with Building Elements, Spaces and have control over representation. Introduction This article gives an overview of several recommendations and tips, to better apply BIM applications and BIM methodologies, in the context of the early design phases. Many of these tips are applicable in any BIM application and they are based on experience gathered from teaching, researching and using BIM software. Sometimes they could help software developers to improve the workflow of their particular BIM implementation. Tip 1 : Gradually increase the amount of information In the early design phases, the architect makes assumptions and lays out the main design in

Getting BIM data into Unity (Part 9 - using IfcConvert)

This is part 9 of a series of posts about getting BIM data into Unity. In this post, we’ll discuss the IfcConvert utility from the IfcOpenShell Open Source IFC Library to preprocess an IFC model for integration with Unity. This is (finally?) again a coding post, with some scripts which are shared to build upon. Conversion of IFC into Unity-friendly formats The strategy with this approach is that you preprocess the IFC-file into more manageable formats for Unity integration. Most Web-platforms do some sort of pre-processing anyway, so what you see in your browsers is almost never an IFC-file, but an optimised Mesh-based geometric representation. However, it wouldn’t be BIM-related if we’d limit ourselves to the geometry, so we will parse the model information as well, albeit using another, pre-processed file. IFC to Wavefront OBJ I used a test IFC-model and used the IfcConvert-utility converted it into OBJ en XML formats. The default way to use it is very simple:

Getting BIM data into Unity (Part 8 - Strategies to tackle IFC)

This is part 8 of a series of posts about getting BIM data into Unity. In this post, we’ll discuss IFC as a transfer format towards Unity. As with the previous post, this is not a coding post, although hints and examples are provided. Open BIM and IFC Everybody who ever met me or heard me present on a conference or BIM-lecture will not be surprised to hear that I’m a strong believer in the Industry Foundation Classes (IFC), an open standard, with already two versions published as an ISO standard, being IFC2x2 and IFC4 (but surprisingly not IFC2x3 which is widely used). In the ideal world, this would be the format to use to transfer BIM data into another environment, such as Unity. So what are our options? Looking in the Unity Asset Store Assimp is a library which supports multiple formats, including IFC. https://assetstore.unity.com/packages/tools/modeling/trilib-unity-model-loader-package-91777   I did a few attempts, but alas without any success. It is possib
