    How to build a Helical Circular sweep?

    I am trying to create a part which looks like in the image. My sweep function fails when I try to match the dimensions from image. Any suggestions would be highly appreciated. Thankshttps://files.engineering.com/getfile.aspx?folder=45d4b180-153e-41ed-b0b3-603b39c4dbd4&file=Precatenanes.SLDPRT

    Script to generate edge set from different CAD models

    Hi, I used abaqus macro recording when defining set: by edge(20 deg). My end goal is run through the script different models/geometries which are identical in every aspect except for a few parametric values. For both models, I am using the same procedure for selecting the highlighted...

    Selecting all edges in python scripting to create wire

    Hello, Goal is develop a script to create wire from edges-selecting all the edges. Used macro recorder and then using the .jnl file as reference for the scripting. .jnl shows the following line for the command >create wire by selecting all edges: e = p.edges p.WireFromEdge(edgeList=(e[0], e[1]...

    Mass scaling accuracy

    Hi, I am using mass scaling for my analysis. The documentation for abaqus indicates that mass scaling should be used with caution: "However, you must ensure that changes in the mass and consequent increases in the inertial forces do not alter the solution significantly." The status file or...

    Ansys Beam Model- Mesh

    Hi, I have been using abaqus for my analysis until now. However, a limitation in the program prevents adaptive meshing of beam elements. This is crucial for me as the results from analysis are seen to be highly dependent on the mesh size used. I am hoping that Ansys does not have such a...

    Applying tension to 3d knityearn

    Hello, For my project, I wanted to study the effect of yarn tension. Is there a way to add pre-tension to the yarns in abaqus? I have attached an image for reference. There are facilities for pretension in a bolt/bar however those example are fixed in directional. What I find challenging here is...

    Beam element meshing

    Hello, I am working on a model with beam elements on wires. My concern is that the results/analysis have huge variation depending upon the mesh size I use. As I recollect mesh sensitivity analysis for beam elements is not yet permitted in abaqus. With this view, how can I determine what is the...

    Export beam element ODB file to CAD

    Hi everyone, I am looking for a method to export the deformed shape into a CAD program. I found a post earlier which provided a method, but unfortunately it doesn't work for beam element. "No facet data found. STL Export failed" Here is the advised for the earlier post...

    Adaptive remeshing for wires

    I am trying to work with wire sections and ran into this issue. -"wire regions are not allowed for remeshing rules" Are there any workarounds to this? I could make them a solid elements but then I would spend a lot of time in building the mesh and other unknown errors. _skr3178

    Parition wire instances at assembly level to apply different materials

    Hi, I am trying to partition a set of wire instances at the assembly level using sketch. However, Abaqus does not allow that; no faces/cells are recognized. Attached image to show the details. My goal is to create the partition so as to apply different materials to the sections. I appreciate...

    parametric study on 3d sketch

    Hi, Is it possible to perform a parametric study on the geometry dimensions of a 3d sketch in abaqus? Currently, I am importing the 3d geometry from solidworks and creating wire by eliminating certain edges. Thanks and sincerely...

    Copying constraints when using linear pattern

    Hi, In my model I have over 100 instances which have been developed from 2 instances. The pattern feature does not copy the model constraints although the sets defined at the part level are copied. I found an unanswered question on the forum which is the same topic...

    Connection between beam nodes

    Hi, I am trying to model two beam elements by using wires. I would like to create a constraint/ connection between wires such that at these connections the wire nodes are allowed rotation but disabled translation motions. The 2 beam element splines are based upon the center line of the beam...

    Non-linear thermal buckling

    Hello, I am working with a plate with zero translation boundary conditions at both ends and application of loads in the form of thermal predefined temp. from 250 to 450 deg. C. Thermal coeff of expansion has also been defined for the material. INP files: Linear: https://gofile.io/d/0ZZCJt Non...

    Why do sets defined in Assembly become undefined?

    Hi, I have prepared a model with several instances in the assembly. At the assembly level, when I suppress and then resume the instance, the set definition is lost. The instances are not deleted btw. Does anyone have any suggestions on why this happens and a possible workaround through it...
