PBEAM fatigue analysis

I'm trying to make a fatigue analysis of a chassis. I meshed the chassis by 1D line mesh with PBEAM property.

On FATDEF I put the option PBEAM in PTYPE area and when I try to analysis was showed the follow message:

*** ERROR # 6817 ***
PBAR/PWELD only can be used for spot weld fatigue analysis. PFATSPW
is required for spot weld fatigue property.
FATDEF ID = 9
PBAR/PWELD ID = 3
PFAT ID = 8.

How I complete my fatigue analysis of my 1D elements?

Hi @Thiago Marinho

1D elements can be used for spot weld fatigue analysis only,

Instead you can use 2D elements on your chassis for fatigue analysis

Thank you very much!!

Have any method to convert the 1D line with PBEAM by 2D representing your section? I think doesn't.
