# How to model a vessel or a tank?

Contents

There are two methods:

• The first method is used for vessels with vertical walls
• The second method is mainly used for vessels with curved walls

## Method 1

• Enter the perimeter of the vessel in a top view.
• You can use the drawing function .
• You can use the tool for parametric shapes (circle and rectangle) .
• Or you can import a dxf-file.

No matter with tool you use, make sure the perimeter is not too detailed. Avoid lines smaller than 10 cm.

For example, a circle with radius 3m and 16 divisions.

• Remove the center point.
• The next step is copying the perimeter.
• Select the perimeter.
• Click on . Ask one copy. Specify the distance. Here 3m. And don’t forget to generate the connecting surfaces. Click ‘OK’.
• Change the section and material of the walls as desired with .
• The final step is generating the baseplate.
• Select the lower perimeter and click on  to generate a plate.
• Change the section and material of the baseplate as desired.
• After assigning supports and loads, this model can be calculated.

## Method 2

• Enter the perimeter of the vessel in a front view.
• You can use the drawing function.
• You can use the tool for parametric shapes (circle and rectangle).
• Or you can import a dxf-file.

No matter with tool you use, make sure the perimeter is not too detailed. Avoid lines smaller than 10 cm.

For example, this curve imported using a dxf file.

• The next step is copying the perimeter.
• Select the wall shape.
• Click on . Ask 16 copys, select the rotation plane (XZ), and specify the angle (22.5° = 360°/16).Don’t forget to generate the connecting surfaces. Click ‘OK’.
• Change the section and material of the walls as desired.
• The final step is generating the baseplate.
• Select the lower perimeter and click on to generate a plate.
• Change the section and material of the baseplate as desired.
• After assigning supports and loads, this model can be calculated.
