Explanation

Input of geometrical data

Enter shell data

Especially with very long shells, the considered length can differ from the actual shell length.

Action

What you see

Explanation

Use nozzle specification

If you use the nozzle specification from the NozzleSpecApp, the forces and moments are taken from this specification and entered automatically.

Enter nozzle data

Geometrical data and position of the nozzle. When you are using DIN nozzles, you can select the nominal diameter DN.

Specify tangential nozzle

Specify reinforcing plate

If there is no reinforcing plate, just leave the fields empty

Documentation

You can save the FE documentation as RTF file by selecting ‘File – Save”. This RTF file is integrated into the FEM documentation and can be printed as one whole file.

Action

What you see

Explanation

1. Create the FE model

2. Start the FEM calculation

This is the central mask of the FE calculation.

All actions can be controlled here

Action

What you see

Explanation

Select ‘Documentation’

When the FEM calculation is finished the documentation can be created.

Action

What you see

Explanation

Now select

„Membrane stress“

In this mask, the documentation is created automatically.

As soon as the mask is loaded you receive information about the utilization of your configuration.

Action

What you see

Explanation

Move the mouse with pressed left key to change the size.

Move the mouse with pressed right key to rotate the model.

Mask for presentation of stresses and displacements.

Click on 

„Display node stress“

This button activates the presentation of stresses.

Element stresses and displacements

Action

What you see

Explanation

Press the button

„deformed
 system“

You may freely resize and rotate the 3D stress model with the mouse.

For rotation keep the right mouse button pressed, for sizing the left mouse button, and move the mouse over the model.

Use the

Copy button

This button copies the current view.

An automatic copying of the graphics is not possible.

You may freely position the view of the nozzle at your desire.

Action

What you see

Explanation

Here you may also print or save the documentation or cancel the presentation.

Stresses and views can be easily integrated into the documentation.

Additionally you may also enter your comments or own CAD graphics

Action

What you see

Explanation

Press

„Fatigue Info“

To show the S2 stress range

Action

What you see

In the LV module  WRC

Press the button

„Proof by finite elements method“

The calculation of stresses in cylindrical shells with nozzles under nozzle load is too inaccurate with WRC or even impossible.

In this case you can easily start an FE calculation.

Values already entered into the WRC module are automatically transferred to the FEM module.
