Fail to assign Structured mesh 1

[Mohamed Zied]

Hi,

I am creating a model for an I steel girder with connecting many parts. I meshed the assembly, but I couldn't assign a structured Quad mesh.
Will it affect the result if I conduct the analysis using a non-structured mesh as you can see in attachments?
By the way, is it better to mesh the assembly or each part aside?

 

[FEA way]

In many cases structured mesh can be used after partitioning. However some models are too complicated to use this type of mesh. It's absolutely normal to use non-structured mesh in such case (as long as its quality is not too low).

When it comes to the second question - it's up to you. You can use dependent or independent instances, whichever is more convenient for you.
