This month’s webinar will cover meshing of native geometry in Abaqus. A short section on processing geometry to improve mesh quality will be followed by a discussion of the various meshing techniques available to the user. The webinar will conclude with a brief introduction to the tools available for working with non-native meshes in Abaqus.
In this blog post, we will be discussing about the translucency feature, that is there to help us enhance the results presentation of our fe analyses from within Abaqus Visualization.
Lately, I’ve received a few questions related to python scripting. It is a nice way to add to the default Abaqus functionality and automate repetitive work. Here I want to give a few tips that may help when you are creating your first Abaqus python scripts.
In the past, the reliability of some products were assured by keeping the mass of those relatively high. When computers started being a tool available for all, engineers began using them to calculate what is the likelyhood of failure. With this approach, weight of products was reduced and theirs reliability increased (or at least kept at the same level).
In this blog post, we will be showcasing a fatigue assessment of a bicycle frame. This fatigue assessment will be against certain cyclic loading scenarios. Cyclic loading scenarios, typical for bicycle manufacturers, can include, pedaling forces, horizontal forces acting on the front fork and vertical load acting on the seat post.
Problem solving and simulation within the Oil and Gas industry use approaches that are generally familiar to other more mainstream mechanical engineers, but often require the use of specific, often codified, processes and tools.
This webinar will look at some of the tools that are available within Abaqus that allow an in-depth insight into the behaviour of systems in ways which conform to accepted standards in Oil & Gas industry. These include:
On many occasions, particularly when our model size is large or when automatically generated Field/History outputs are used by default, the resulting output database of an analysis can be of significant size. Typically (at least for quasi-statics, statics), the user is mainly interested in retaining the first and/or last frames of generated output, as the main focus is the final deformed configuration, when a loading has been fully ramped up (100% loading). Additionally, when automatically generated output requests are used, predefined default output variables are written in the results database, whereas the user might only have interest in von Mises stresses and resulting displacements in the model.
In this blog post, we will be showcasing the OEBT plug-in, that allows the user to select the specific results that they would like to keep, and populate them in a new results' database.
- Mesh-independent fasteners couple layers of material to each other, simulating the effect of e.g. spot welds.
- They don’t require the coupled region to be separated from other regions by a partition (mesh-independence), making them easy to define.
- Instead their position is defined by attachment points, reference points or nodes.
- It is possible to create patterns of attachments points, to easily define the location of multiple fasteners.
- Fastener are defined from the interaction module, via “special”, “fasteners”, “create” or the “create fasteners” icon.
- Rigid MPC fasteners are possible. The behavior of the fastener can also be defined via a connector section to allow more complex behavior.
- Abaqus allows you to continue a previous analysis with a new analysis.
- Restarting is only possible from increments for which restart files are available for the previous analysis.
- These are requested before the previous analysis is run, from the step module, via “output” “restart requests”.
- In the model attributes of the new analysis you can refer to the step of the previous job that should be used as starting point.
- It is possible to continue an interrupted job as it was originally defined, or to add additional steps.
- Because additional steps are a continuation of what was done before, it is not possible to include new geometry etc.
- Select ‘restart’ as job type when running the restart analysis
- The .odb of the restart analysis will only contain data of the newly simulated steps, so the output is split over two odb's.
Simuleon is organising another unique hands-on workshop called "Introduction to XFlow CFD".
Our classroom style workshop will be held in English language at our office location in 's-Hertogenbosch, the Netherlands. This is the ideal way to understand and try-out, what advanced CFD simulation, with SIMULIA XFlow CFD can offer.
