Experimenting with @Blender #animation and #visualization tools these days for implementation in #structuralengineering, in this case with the response of a vault roof, created by @brunopostle with his #Homemaker add-on, under gravity loads.

Performance data: significantly reduced calculation time; response may differ compared to full model, so it is advised to have a representative comparison for your case study.

New tutorial on the use of the Craig-Bampton dynamic sub-structuring method in @CodeAster to perform nonlinear dynamic analysis with super-elements of the elastic parts of the structure. Video: youtu.be/FWYTCt2s0A8 Code: github.com/Jesusbill/code-as… #fea #opensource #OpenScience

@OSArchOrg Monthly Meetup, tomorrow Saturday 6 at 20:00 UTC. Two keynote presentations by Thomas Hächler and Cyril Waechter, the first on a web-based BIM platform and the second on Building Energy Modelling (BEM) based on BIM. More info here: community.osarch.org/discuss… #BIM #BEM

@Blender & @CodeAster : two #opensource superpowers that can form a great squad! 🥳🥳 @BlenderBIM #osarch #ifcopenshell #openBIM

New #Tutorial on Modelling of #Nonlinear #Uplift and #Rocking Dynamic Response of a Structure in @CodeAster and #Salome_Meca is now available in our YouTube channel! Video: youtu.be/s9dH7wyoewk Files: github.com/Jesusbill/code-as…

In fact the execution time for this example is close to 1/10th

New tutorial on using a modal base for linear dynamic analysis with @CodeAster Reduce analysis time to a fraction wrt the physical base model without loss of accuracy, as long as the mode shapes are correctly selected. Video: youtu.be/faFMYlkHM0g Code: github.com/Jesusbill/code-as…

#IFC-To-@CodeAster Update Connections along a line added which permits to define the degrees-of-freedom to be constrained between walls, slabs etc. based on an arbitrary LCS. Two new examples, slab_01 and structure_01, added in the repository within the #IfcOpenShell project.

[2/2] In this example, a grid of beams is analyzed, with center-line modelling and rigid links for the correct length and position of the structural elements. Various cases for the connections are considered: rigid, pinned, or flexible, with user-defined stiffness, conditions.

[1/2] Implemented all types of point connections in #IfcOpenShell IFC2CA Project including: - internal releases/springs for each DOF - rigid links in series with internal springs - external springs for point supports Code: github.com/IfcOpenShell/IfcO… Models: github.com/IfcOpenShell/anal…

New tutorial on the connection of non-conformal meshes in @CodeAster. One of the best out-of-the-box features that allows meshing independently parts of a model and combining topologically conformal, yet independent, meshes for linear analysis. Video: youtu.be/4peRNehSsj4

New "How-To" video on performing a Linear Transient Dynamic Analysis in @CodeAster with acceleration ground-motion time-histories. Video: youtu.be/QoaNW4zC5u0 Code: github.com/Jesusbill/code-as… #opensource #tutorial #Engineering #earthquake #finite_element_analysis

We also show how we can use @ProjectJupyter to read and plot data from our text file results produced with Code_Aster. Jupyter notebooks are a really nice way to post-process our results. The related files can be found in the GitHub repository

New "How-To" video on performing a multi-step analysis in @CodeAster with material and geometric nonlinearity with an elasto-plastic material with kinematic hardening and large deformations with logarithmic strains. Video: youtu.be/3z35NDNWV78 Code: github.com/Jesusbill/code-as…
