## 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

• In Atelierul FEM, click pe or select ModelMechanical ConstraintsConstraint force pentru a deschide dialogul proprietăților Force Constraint

• 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

2) Applying a force in to line in selected direction

• In FEM workbench, click on or select ModelMechanical ConstraintsConstraint force to open Force Constraint properties dialog
• 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 line segment to which a force should be applied. It will appear in the list of geometrical objects.
• Fill in Area load with a force value in [N]
• Direction: Acum, cu segmentul de linie selectat, probabil că forța este aplicată într-o direcție greșită. Trebuie să specificăm direcția făcând clic pe butonul Direction și apoi făcând clic pe o fațetă care indică direcția sa normală în direcția forței (sau direcția inversă). Din nou, puteți reveni la direcția forței făcând clic pe Reverse direction.
