when calculating loads

1 in stress analysis environment

2 in autodesk nastran environment

i have different offset data what

i am doing wrong?

initial data

1 frame 5000x5000x3000 mm

2 profile square pipe 100x100x7 mm

3 load 10000 kg

I see a finite element analysis (inventor) and a beam analysis (Nastran).

Am I wrong?

Linear Static in both options

No i didn't say that.

The order between tetra and linear elements is different.

From your pic (it seems) you are comparing a linear analysis with tetra elements (in Nastran) with a linear structural analysis in Inventor (beam linear elements).

Can you attach it with your analysis setting(both cases)?

Inventor 21,38 mm (frame analysis)

Nastran 21,97 mm (frame analysis)

Tip 1. When you Pack and go - Templates are not needed and usually not Libraries and Styles.

Question 1.

You posted a question about Frame Analysis - yet there is not Frame Analysis in the dataset that you Attached? How can the issue be diagnosed without the full data?

I don't see your Constraints?

I don't see your Loads?

I have attached the experiment file.

if there is a video or training video

I will be very grateful

I get an offset of 38 mm

1 fixed on the plane

2 plane pressure

(10,000 kg * 9.8) / (0.325 m ^ 2 * 4) / 1,000,000 \u003d 0.076 MPa

What am I doing wrong?

apply force along the plane
