With the Live Parts™ for SOLIDWORKS Add-in, users can define forces that act upon their Live Parts design. You can define forces using one of two methods outlined below.
- Select Force in the Add-in toolbar.
- Use the Force Type drop-down list to select the type of force (linear, pressure, or rotational).
- Input the values for the force direction as numbers or expressions in the X, Y, and Z directions.
- (Optional) Click on the Direction dropdown menu and click on Selected entity to instead define the force direction by selecting an entity (i.e. line) in your SOLIDWORKS assembly.
- Click on the Surfaces box and select the surface(s) in your SOLIDWORKS assembly to which the force will be applied.
- Select the Force application method (under Parameters) to specify how the force will be applied to the chosen surface(s) - push, pull, or both.
- Click on the Magnitude box (under Parameters) and input the magnitude of your force in Newtons.
- Click the Checkmark on the top of the force menu to accept the changes.
Notes on forces
- Forces are applied to cells that make contact with the force's surfaces. Users should select force surfaces that are coincident with surfaces of fill, exclude, and contain zones.
- If a user selects a surface of a fill zone as a force surface, then the cells that grow within the fill zone and touch this surface will feel the force. Make sure to specify the direction of the force and the force application in a way that makes sense. For example, if you select the top surface of a beam to be a force surface, and you specify the force to be downwards, and you specify the force application to be "push" then this makes sense. In the same example if you specify the force direction to be upwards, then the force application should be "pull", as in pulling the beam upwards. For simplicity you may specify the force application as "both" to ensure that forces in either direction will be applied.
- If you specify multiple surfaces to apply a force, then the force will applied proportionately across those surfaces based upon the surface area of each surface. For example, if two surfaces are selected and one has three times the surface area of the other, then 3/4 of the force will be applied to the larger surface and 1/4 to the smaller one.
- If the user selects a force surface that touches multiple fill zones, then the cells from different fill zones that grow and touch that surface will feel the force. For example, suppose a user created a cylindrical shaft surface that passed through two separate collars that surrounded it. Next the user selects the cylinder shaft as as a force surface. When the cells now grow make contact with the fill zones, and, in turn, fill these zones up, the cells from each fill zone that touch the force surface will feel the force in proportion to the size of the surface areas of the fill zones touching the force surface.
- It is possible to create surfaces as force surfaces that touch only a portion of a fill zone face. For example, if a user wanted to apply one or more different forces to a region of a shoe sole, s/he could create one or more surfaces resembling topographical map lines, or contour lines, and apply different forces to each region. The cells within the fill zone (i.e. shoe sole) would touch different surfaces and each feel different forces.
