Descriere
Această comandă aplică o forță de valoare dată [N] la geometria țintei selectată.
Cum se folosește
1)Aplicarea unei forțe în direcția normală a unei fațete
- If you have Mesh displayed, you need to hide it (select the mesh object and press spacebar or right click and select Hide item) and show the original model.
- Click on a face to which a force should be applied. It will appear in the list of geometrical objects.
- Fill in Line load with a force value in [N] (attention: Not in [N/m])
- Direction: In a typical case, you'll click this field empty to apply a force in normal direction to the face. You can revert the direction of the force by clicking Reverse direction. In other cases, you need to pick a face or plane, which is in normal to the force direction (it could differ from the face, to which the force is being applied)
- Click pe obiectul Close to finish the dialog and create ConstraintForce
Notes
- The defined force is applied uniformly to the selected objects. For example, if you define one force load with 200 N applied to two faces having the same area, each face will be uniformly loaded with 100 N.
- This feature uses the *CLOAD card in CalculiX.
