Hello,

I was trying to simulate the progressive element activation in a cylinder. Would anyone suggest to me how to generate an event series for the addition of material in cylindrical coordinate?

 

[FEA way]

The cylinder is very thin and meshed with just one layer of elements in the through-thickness direction. This makes it difficult to obtain good results. You could try increasing the size of the box for the uniform heat source, maybe also positioning the path differently (for example, slightly above the model and corrected with proper offset or box size values). Check different types of heat sources as well.

How have you eventually managed to prepare the path for the event series in this case ? Manually or with the help of some g-code generator ?

Dear FEA way,
Thank you for your reply. I will try and get back to you. I used Excel to generate the event series.

I tried all the tips that were offered here and I still managed to get the desired result. Although it was a bit difficult, it still does not compare to how I wrote an admissions essay at university. I had no idea it would be such a challenge when I saw what was needed. But then the guide [URL unfurl="true"]https://studymoose.com/university/wake-forest-university[/url] helped me and there was even an example. So for me it was much more complicated than setting up a program and writing a script in python, that's how I am. I don't really like to write.

Dear FEA way,

Greetings, I was trying to simulate the progressive buildup of a simple rectangular bar using the AM module of Abaqus 2022 and I got the following error message when I tried to submit the job:
"the region selected for the following element progressive activations contains invalid geometry or mesh components"

What would be the problem?

Regards,

Kasahun

It's hard to say without the file. Maybe element type not supported by AM features is used. Also, make sure that you select only the region of the model which is supposed to be printed.

Dear Kasmat2013,

Thank you for your useful information. Can you give more information about the generation of event series from G-code using Excel? Is it possible to share your Excel file?

Thank you
