Spotweld

Altair Forum User

Hi,

 

I have a question on spotweld connectors. I have the following two components with shell mesh. I have a hard time choosing which option to use in spotweld. Pls help me. Please explain which one we should use and when?

<?xml version="1.0" encoding="UTF-8"?>

 

1) Mesh Dependent - adjust realization- find nearest nodes

2) Mesh Dependent - adjust realization- project and find nodes

3) Mesh Dependent - adjust realization- ensure projection

4) Mesh Dependent - adjust mesh- remesh

5) Mesh Dependent - adjust mesh- smooth

6) Mesh Dependent - quad transition- imprint

7) Mesh Dependent - quad transition- skip imprint

 

Which method is good and if I use different methods will I get different results?

I have used (Mesh Dependent - adjust mesh- remesh) but then I feel that when I do this because of remesh my elements become smaller and fail in quality. 

 

Thanks,

Datta

Hi Datta,

Please download the free e book Practical Aspects of Finite Element Simulation (a Study Guide)  from http://www.altairuniversity.com/free-ebooks-2/ . 

Connectors topic is well covered in this e book (page 157 onward) and most aspects you listed above is also covered in this e book.

Thank you George and Rahul for the reply. I went through the Tutorial and the ebook, but I could not find an answer for the same. I want to know which one to use, because I am really stuck at this. Please help me!

Hi Datta,

You can go for mesh independent option so that the existing mesh will not be changed.
