    how to assign contact property to line body (beam)?

    Hi, I am new to Ansys and I am trying to simulate pulling two curved beam, joined at one end point, straight and during the process, the beams will touch one another. I am having trouble trying to assign some kind of contact or interaction (hard contact, rough surface) so that the beams don't go...

    how to assign self-contact property to beam

    Hi, I am new to Ansys with some experience with ABAQUS. I am trying to simulate pulling a curved beam straight and during the process, the beam will touch itself. I was able to do this in ABAQUS but in Ansys, I am having trouble trying to assign some kind of contact or interaction (hard...

    making a hexagonal network of connectors consisting of 1500 connectors

    Hi Barten, Thanks a lot for your help. I was able to play around with the simulation during the weekend. As you suggested, after I added inertia to the nodes, I can run it in Dynamic, Explicit mode. However, I find that the mass introduces oscillation to the node movement. I guess I...

    making a hexagonal network of connectors consisting of 1500 connectors

    Hi, Thanks for the script. Now I can start the actual simulation process. I did some copy and paste of your code to make another .py file for the case where I do everything in CAE up to the point where assembly-level wire needs to be formed, then run the script to: 1) Partition edge in...

    making a hexagonal network of connectors consisting of 1500 connectors

    Hi, yeah, a lot of questions and thanks for your patience. I originally made the hexagonal layout in AutoCAD and export it to .sat to be imported into ABAQUS/CAE's sketch. If it's too much trouble to change to code, I am thinking your two-part script will work fine, as I will make minor...

    making a hexagonal network of connectors consisting of 1500 connectors

    Barten, One follow-up question please: I can create a sketch of the structure I want easily; so, is it possible to skip the "sketch" part of the "hexagon" definition code and replace the following line myPart.BaseWire(sketch=mySketch) in "part" with myPart.BaseWire(sketch="?? reading...

    making a hexagonal network of connectors consisting of 1500 connectors

    Barten, Could you verify something for me? I was able to create the hexagonal wires with your script. But it seems that I cannot edit the part without creating errors. That is, if I go to the sketch to delete a line, the wire feature will fail to regenerate and as a result, all of the...

    making a hexagonal network of connectors consisting of 1500 connectors

    Hi Barten, Thanks a lot; this is a very helpful starting point for me. A few questions: 1) it seems that the variable user_length is only used to form connectivity between nodes that are close enough together, correct? I am asking because I might have 6 segments that are a little bit...

    making a hexagonal network of connectors consisting of 1500 connectors

    Hi Barten, I've attached an input file I created using CAE. The coordinates of a smallest hexagon is in the beginning of the file. I'd like to use axial connector with elastic behavior with a tabulated list of force vs. displacement. This is also included in the .inp file. And...

    making a hexagonal network of connectors consisting of 1500 connectors

    Hi, I am planning to simulate a hexagonal network of 1500 nodes with a connector element connecting between each adjacent node pairs. The connectors are used to simulate a variable-stiffness spring as it's being stretched. I am currently using ABAQUS/CAE as the preprocessor and the only...

    spring with variable stiffness (spring constant) depending on its disp

    Thanks Martin, The error message is "10 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection." I am attaching the .inp for parts and assembly portion below. So, can I simply delete the part's instance in the assembly portion? can I...

    spring with variable stiffness (spring constant) depending on its disp

    Martin, Your suggestion works! Thanks. Two more follow up questions please: 1) I could only proceed with running job files if I have an actual material element between the connector element (i.e. create a line and mesh it, assign section to it as usual and then create another wire on top...

    spring with variable stiffness (spring constant) depending on its disp

    Thanks Martin, So, I will also need to call a user subroutine to get the displacement value to be used as the dependent variable, correct? Thanks.

    spring with variable stiffness (spring constant) depending on its disp

    Hi, Could someone please offer some suggestions to what I thought was a simple modeling problem that turned out otherwise? I am trying to model, using ABAQUS/CAE, a spring element with variable spring constant depending on its displacement according to a list of tabulated values. The spring...
