Assembly
Summary of available functionality for defining the properties and behavior of parts in the model.
- Materials
- Rigid Parts
  A rigid part can displace under the loading, but only as a rigid body, i.e. without deformation or strain.
- Spots
  A Spots is a feature that enable applying loads, constraints, or other boundary conditions (BC) to local regions on the surface, instead of applying BC to the whole faces of the model
- Create Coordinate System
  Define a local coordinate system to which boundary conditions may be later applied.
- Import Coordinate System
  Import coordinate system from an external comma separated values (CSV) file. Multiple coordinates can be imported at once.
- Create Line on Part
  Create a line that can later be used to generate seam welds.
- Create Sheets
  Create a sheet from an imported surface by applying thickness.
- Create Laminates
  Create laminate from an imported skin
- Set Part Type as Bolt
  Define parts as bolts.
- Set Orthotropic Material Geometry
  Define the material orientation of the part.
- Import Datum Points from CSV
  Import datum point sets from an external comma separated values (CSV) file.
- Create Liquid Body
  Create a liquid body between selected faces.
- Create Gas Body
  Create gas body between selected faces.
- Assembly Review
  You can clean up the geometry in your model by removing undesired parts.

Frequently Asked Questions

Create Liquid Body

Create a liquid body between selected faces.

On the Project Tree, click on the Assembly workbench.
On the Assembly workbench toolbar, select > Liquid.
In the modeling window, select parts on the model.

Note: Liquid body can only be applied to faces.
Optional: Select the Add tangent faces check box.
In the drop down menu, specify the Mass units.
Specify a value for the Total mass of the liquid.
Click OK.

Comments

The selected faces should be the wetted surfaces that are in contact with the liquid.
The liquid is assumed to be inviscid and incompressible.
Sloshing effects are not considered.
It is recommended to have the liquid body fully enclosed in a structure.
If free surface of the liquid body is expected, see below:
- If liquid body is applied on a flat plate, a thin layer of liquid is assumed.
- In case of open containers, the free surface is determined by the shortest path between free edges.
- The free surface of the liquid is assumed to remain unchanged during the solution.
Liquid body application results in the following effects:
- Adds distributed mass to the structure and, therefore, changes its inertia and dynamics.
- Incompressible fluid can significantly change vibration modes and general deformations at fluid enclosure because the volume of the enclosure is always preserved.
