    Cohesive behaviour relative displacement

    It does point to the line containing Frame.fieldOutputs[]. If I use Frame.fieldOutputs['CDISP'] I get 'KeyError: CDISP'

    Cohesive behaviour relative displacement

    I have realised one more thing regarding my second question. I think I have used the wrong words. I said I want to find the relative displacement when the surfaces in the contact pair are 'not in contact' or have 'separated'. However, I meant to say this considering the cohesive bond has not...

    Cohesive behaviour relative displacement

    Hi FEA way Thanks for replying. 1. I do think an instance can be a region for getSubset() (I am successfully using it to extract other results from an instance). Nevertheless, I noticed now that in my input file CSLIP and COPEN is not requested under *Contact Output, even though I can view...

    Cohesive behaviour relative displacement

    Hi there I have two questions related to surface-to-surface contact with cohesive behaviour: 1. How do I access CSLIP and COPEN field outputs using scripting? The following gives me a keyword error for CSLIP and COPEN using fieldOutputs[]: CSLIP_values =...

    Scripting - Extracting envelope stresses from elements.

    Hi there I am using scripting to extract stresses from shell elements. The problem I can't solve is how to extract the max envelope stress for each element. I use the following statements in my python script to access stress (before specifying invarients): S = Frame.fieldOutputs['S'] ElemSet =...

    Cohesive behaviour - stiffness vs displacement inconsistent

    Thank you for the replies. The problem is indeed the discretization method and my apparent lack of understanding the differences in the methods. Node-to-surface results in expected displacements. Thanks FEA way for referring me to the Verification Guide, this I have not used before.

    Cohesive behaviour - stiffness vs displacement inconsistent

    Hi there I am testing the use of surface-to-surface contact interaction with a cohesive behaviour contact property. However, I find that my model is not matching a theoretical calculation and the behaviour is not consistent across different stiffness values(Knn, Kss, Ktt). Model description...

    Edit ply thickness with script

    Hi there I am trying to write a script to change the thickness of specific plies in predefined composite lay-ups. It seems that the only way to edit the thickness of a ply is to redefine it. The problem is that I need the 'region' as an argument for the CompositePly() object. I do not know how...

    Virtual topology causes mesh to be deleted

    Thanks for the reply. Yes, remeshing is quite a straight forward task. In my case, it is a bit tedious though. My model is very big and I always run into trouble with some areas of the geometry not being able to mesh. At the moment I am considering merely editing the geometry in Abaqus so...

    Virtual topology causes mesh to be deleted

    Hi there I have used virtual topology on the geometry of my part to improve the top-down mesh that I generate. The problem I now have is that every time I delete any part of the geometry (a face for example), the entire mesh of my part is deleted as well. The geometry of my part was imported as...

    Applying an inertia relief load

    The results look indeed as I would expect them. Thank you for the answer. It looks like I missed this rule about the number of warnings.

    Applying an inertia relief load

    Hi there I am trying to understand how to apply an inertia relief load, but I seem to misunderstand the set-up. I created a simple model consisting of a rectangular plate in the X-Z plane. I want to use an inertia relief load to prevent rigid body motion in the Z-direction. So I constrain the...

    Object selection with script

    Excellent! Thank you Mustaine3 for the help. I tried SetByBoolean() and it worked.

    Object selection with script

    Hi there, I am using the statement getByBoundingBox() in my Python script to select vertices or nodes in my part. I am looking for a method of selecting vertices and nodes which are located on a specific set of faces/surfaces. I have created sets of faces in my part. At the moment I can only...
