    ABAQUS: How to create a Set for a WirePolyLine in Abaqus Scripting?

    Thank you FEA way, So the solution is to assign the created wire instance to a variable and then reuse that wire object by calling the variable without needing to know its coordinates, this is straightforward, I should have thought of this..

    ABAQUS: How to create a Set for a WirePolyLine in Abaqus Scripting?

    Hi all, This was a question asked in the past with no answer, thread799-391993, wondering if anyone has found a way to define a set for a wire in Abaqus scripting? In Abaqus, a wire is a feature however the Set() method does not have an argument to receive a feature object and instead, the...

    ABAQUS: Connector Response Not Matching Input

    Hi FEA way, It is always you, thanks very much! I think I found the issue, I was selecting the node of a BEAM element where one end of the connector is connecting to output the section moment and rotation which is the wrong way of outputting the results. I then replaced the node set with the...

    ABAQUS: Connector Response Not Matching Input

    Hi all, I am looking to use a connector element to model the semi-rigidity of a joint in a BEAM element model (BEM). The semi-rigid moment-rotation response was obtained using a SHELL element model and then idealised into the orange curve below (which I will input into the connector element to...

    Got it, thanks very much！

    Abaqus versions compatibility

    Hi all, In my local PC, I have had Abaqus/2019 installed and used it to construct my model, however, I am running the analysis on a higher version i.e. Abaqus/2023. I know this is ok as Abaqus is backwards compatible also as mentioned here by FEAWay...

    ABAQUS: Model not converging after turning on NLGEOM (Even with very small steps)

    ABAQUS: Model not converging after turning on NLGEOM (Even with very small steps)

    I think I might have found the issue. The concentrated load I was applying was too low relatively causing abaqus to think the section was too stiff. I was applying a load at a fraction of 0.001% to the axial capacity of the column. Increasing the load to 1% of that works like a champ. As the 1%...

    ABAQUS: Model not converging after turning on NLGEOM (Even with very small steps)

    Thanks very much mate, I have reattached the link to download the zip folder with .inp and .cae files in it.https://files.engineering.com/getfile.aspx?folder=2bdce269-98f7-4e93-9809-03624bf17777&file=dummy.zip

    ABAQUS: Model not converging after turning on NLGEOM (Even with very small steps)

    Hi FEA way, Thanks very much for replying. I tried the frequency analysis as you have suggested and the connection looks alright, nothing is flying apart. The strangest thing is that the model only converges under a certain combination of load and initial increment. I have tried to play around...

    ABAQUS: Model not converging after turning on NLGEOM (Even with very small steps)

    Hi all, As the subject, the model is running fine with NLGEOM turned off but as soon as I turned it ON, the model struggled to converge. I have reduced the initial and minimum increment step size and increased the number of attempts (I_A) the solver can reiterate with a lower step size and...

    ABAQUS Ductile Damage Initiation Criterion

    Thank you FEA way, I will have a look at the journal again and see if I can find anything useful.

    ABAQUS Ductile Damage Initiation Criterion

    Hi FEA way, Yes, I did watch the video. What I don't understand is how he got the true stress-strain profile after the necking. Surely those formulas to calculate true stress & strain from engineering values don't work beyond the necking. Thanks, Heng

    ABAQUS Ductile Damage Initiation Criterion

    Hi all, Not sure if it was just me who found the description for ductile damage in the ABAQUS manual a little confusing (perhaps misleading). From the example plot taken from ABAQUS manual, clearly, the damage is initiated at epsilon(0,p) and completely fractured at epsilon(f,pl). However, when...

    ETABS model became unlocked after crashed (Results files were still in the same folder tho)

    Hi all, Has anyone of you ever experience a crash that shut down your ETABS model and when you open it again, the model became unlocked? (Note: this crash happens after the analysis has finished). Strangely, when I check the folder where the ETABS result files were saved, all the results files...

    Several scenario loading

    Do you mean a combination of combinations? I think you can do that, just add a new combination and select your "combination with Load A" and "Load B". I am not sure if I am answering your question but I always define dead and live load in 2 separate combinations then later combine them into one...

    Limiting the stress/force of a member in ETABS

    Hi there, does anyone knows a way to limit the shear stress of a beam-like connection in ETABS? I know you can do a Tension/Compression Limit on the axially loaded member but is there an option to limit the shear stress too? To give a clear image of what I am trying to do, imagine you have a...
