mechanical –NX2007(UG) Finite element analysis tutorial 2– Assembly

This example is still explained with aluminum profile as an example , The difference is that this example is an assembly

1 Enter post-processing module

2 New simulation , Parameter default

3 choice fem file

4 Mesh pairing

Select all assemblies , Automatically generate mesh pairing .
This step means , Fit the contact surfaces close together , So as to uniformly analyze the stress conditions

5 Generate finite element mesh

For extrusions such as profiles , Can pass 3D Sweep the network to generate , In this way, the number of grids is relatively small , The cell shape is regular , Analysis can reduce the amount of calculation

At this time, the aluminum profile located in the beam cannot generate mesh , Here's the picture

For the blue aluminum plate , There are blind holes on the side , Therefore, it cannot be directly generated by stretching , These two objects can pass through 3D Tetrahedral mesh generation

A warning pops up , spot yes

At this time, the beam and the aluminum plate above have generated a grid , But the lower column grid disappears

Click on to update You can regenerate the entire mesh


It can be seen that the grid shapes of beams and columns are obviously different , This is caused by different generation methods

6 go to sim file , Generate solution , All parameters are defaulted

7 Generate constraints

8 Generating loads

Select end face

Choose the direction , Down

9 solve

Wait until the solution is completed , Close the pop-up window
