Yes, that is double layer helix. I don't have the parametric form for it though. I will do some more search on it

I got something to work, but only one catch. The ends don't match up! https://files.engineering.com/getfile.aspx?folder=143319a3-3ffb-487a-921f-6753d31549fb&file=Precatenanes3.SLDPRT

Thanks for your advice. I have found help on single helix in parametric form. Any ideas on how to make it for a double helix?Link Thanks and sincerely

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

I think I found the catch. Instead of using getclosest(coordinate=....), I switched to using verts1 = v1.findAt(((0.0, 5.0, 0.0), )) and it worked.

Hi, I am fairly new with scripting and this might be a novice error which I have been trying to work on for several hours. I would like to select a vertice/node from a point closest to (0.0,5.0,0.0). Running the getclosest(coordinate=....) is preventing me from creating a set. When I record...

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...

Thank you a lot Mustaine3. Your suggestion worked very well. I spent a lot of hours yet was unsuccessful.

Still have error TypeError: edgelist; Expected a tuple, found string I could find hint when I expanded the edgelist=(e[9], e[10], e[11], e[12], e[13], e[14], e[15], e[16], e[17], e[18], ... e[19], e[20], e[21], e[22], e[23], e[24], e[25], e[26], e[27], e[28], ... e[29], e[30]...

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]...

Thank you so much FEAway. I have been struggling with this problem for quite some time and would appreciate your input. My energy plot looks as shown below. As you mentioned and also as per manual the KE is roughly 5% of the IE. DOes this look reasonable? ETotal increases as I am heating it in...

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...

Thank you FEAway for your advise. My efforts are focused on working through the abaqus manual for verification of my model. My model seems to not follow the guideline"ETotal should be constant or close to constant". I am assuming that since I am placing it in an oven which heats from 293K to...

Hi, I realized that the total time step has an effect on the final structure. In all the static thermal analysis, I increased the time step from 1.5 to 60s. The results are all in agreement and with the final deformed shape. I would be glad if someone could help me understand how does the time...

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...

hello, I did some further investigations into the effect of mesh size on the final analysis. For a general overview, the overall model dimensions are 10mm diameter. The study is an explicit dynamic type with thermal loading on isotropic material. Below is an overview of the analysis: Bilayer...

I am using wire elements in my analysis. The direction of tension is along the yarn geometry

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...

Hello, I ran some simulation in order to better understand the effect of mesh size. Two identical studies with one done with 12K nodes and second with 75K nodes. Here are my observations. The less dense mesh(12K) seems to be performing better in terms of not penetrating through the beam...
