    Creating a large number of wire elements in abaqus

    If this is going to be something you have to do frequently then you need to learn Abaqus scripting, Python. Basically every time you do something in CAE there is actually a python command run. But learning this will take time, but will pay off huge if you have to do this often. Check out...

    Thought on element selection

    I was really hoping someone would have some practical advise on this, hopefully with some insight beyond strictly the element definitions.

    Thought on element selection

    Before I get to the question, the background. I am solving a 2D plane strain problem. An attached image shows the typical deflections. There are multiple materials and a beam element runs almost horizontally down the center. I have a pretty good handle on what the different options on the...

    How do you make Abaqus remember basic preferences.

    Thank you everyone. All of these little hints have made my abaqus work a lot smoother. Any other good advise along the lines of simple little changes, settings, or tricks to help out?

    How do you make Abaqus remember basic preferences.

    I know when working on a .cae file you can always just do actions in the GUI then go check the .jnl to see what the python commands are to help develop scripts. Is there an equilvalent sort of thing to .odb?

    How do you make Abaqus remember basic preferences.

    How do you make Abaqus remember simple little settings? Example: I often go to odb Display Options and check "Show connectors". I would like this to just always be checked when I open any odb. Example: When I link viewports I have to go through and check the same options each time that I...

    Creating Nonlinear Displacement Constraints

    Thanks, again it was a combination of things. I got the correct output, the trick to visualizing was: ODB Display Options>>Entity Display>>Show Constraints.

    SolidEdge FEA Simulation

    Great summary. How easy is it to parameterize a model? A large portion of my work in Abaqus is taking some base more and paramaterizing it and then doing optimization and case studies.

    Creating Nonlinear Displacement Constraints

    Sort of found my own answer FieldOuput>>Connector>>CTF But when I blot the whole model goes gray. The color scale gives a range which seems okay for the force, but I don't have any way to visualize it because the connectors have zero area and can't be rendered like beam and shell elements. I...

    Creating Nonlinear Displacement Constraints

    Got it thanks. I went with your first option, which still had the same problem, if I assign a force the resulting displacement/strain is a function of the force the the structure around the connector. Example I would not get the same strain if the connector was in rubber vs steel. But I...

    Get Edges of a wire feature

    I have a wire feature created at the assemble level. I need to through a python script create a sets of the edges that make up the wire. I have looked at mdb.models['Model-1'].rootAssembly.features['Wire-1'] but because it is a "feature" it does not have "edges" as a property. To create the set...

    Creating Nonlinear Displacement Constraints

    I have not worked with those so I may be missing something. I have been looking into the dependent amplitude definition this morning. I can apply that to displacement BC but this is still for the displacement in the global system, not the displacement relative to another node, which will also...

    Creating Nonlinear Displacement Constraints

    Is there a way to create nonlinear displacement constraints? In the past I have used constraint equations to control displacement (interaction module>>constraints>>create>>equation) but this method only allows you to enter a linear relationship. In a simple example what I would like to do...

    SolidEdge FEA Simulation

    I currently use Abaqus for all my FE work. I don't actually use SolidEdge, but have heard that it can do FEA analysis. I have also be cautioned about trusting FEA packages lumped in with CAD software. My questions is does anyone actually use SolidEdge for FEA? What do they think? How far can...

    How to define Anisotropic Material in Abaqus?

    If your material is truly anisotropic you need all 21, sorry. To say how to calculate them would be like saying I have a modulus now I want to calculate my Poisson's ratio for isotropic material. You simply can't do it, it takes two independent values for an iso material, just like it takes 21...
