    How to build a Helical Circular sweep?

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

    How to build a Helical Circular sweep?

    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

    How to build a Helical Circular sweep?

    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

    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

    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.

    Script to generate edge set from different CAD models

    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...

    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

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

    Selecting all edges in python scripting to create wire

    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]...

    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

    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...

    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...

    Beam element meshing

    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...

    Beam element meshing

    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...
