I am trying to model a K Joint. I used surface line to cut a section in the chord thickness through the weld brace and weld width. I used solid edit,, trim with lines, with sweep lines and use Y axis for the direction. But after the trim I get distorted section as shown in Fig 2. What could be the possible cause of this

Figure 1: Quarter section of K joint

Figure 2 using with sweeping lines

Fig 3 : the distorted section where i cannot do meshing
can anyone please help me to resolve this issue

Hello sbhbajra,

It's hard to explain from the pictures.
Can you upload the model?
What HyperMesh version are you using?

Best regards,
Gunter

I have uploaded the model. I have used hypermesh 21. If you could see in the model, i have been experiencing additional problems, the distortion of meshing in the brace

I would be grateful if you could help me

I would recommend to remove the cuts at the opposite side of the tube.
This can be done via Boolean operation combine.

It's also a geomtry visualization issue.
Hide the geometry and you will see that elements are prefectly shaped.

Please find attached the modified model.

Best regards,
Gunter
