Restraints are defined as surfaces that have zero displacement. A simple way to think of them is that they “anchor” the object in place. At least one restraint is needed in every simulation to ensure that the model doesn't experience acceleration or movement.

A load is any force that acts on the model. In Intact.Design, these are vector forces, pressures, torques, and gravity. At least one force must be applied to the model for the simulation to run.

Once both of these constraints have been defined, the simulation can run. Quick scenarios are for those doing a simple simulation or those just starting to work with FEA. If a more complicated project needs to be completed, the stress scenario page will walk you through how to simulate more complex loading conditions.
