## 2.1 Definition and Classification of Loads
A load refers to external forces or constraints that cause deformation or flow in a system. Loads can be classified according to their source and nature as static loads, dynamic loads, periodic loads, etc. Static loads are those that act over a long period with minimal rate of change, whereas dynamic loads are those that cause changes in components within a system over a short period. In Hypermesh, we need to define and classify loads based on specific simulation objects and requirements.

## 2.2 Adding Loads in Hypermesh
In Hypermesh, various types of loads can be added through the load toolbar. Options include point loads, surface loads, volume loads, etc., and numerical values and directions of action can be input in the corresponding load panels, applying appropriate loads to the model.

## 2.3 Methods for Setting Different Types of Loads
Different types of loads have their unique settings methods. For example, point loads require specifying the point of action and direction; surface loads require specifying the acting surface and load size, etc. When adding loads, it is necessary to select the appropriate load type and settings method based on specific simulation requirements and objects.

## 2.4 Distribution and Mode of Action of Loads
The distribution and mode of action of loads play a crucial role in simulations. By setting loads with different distribution methods, various real-world load situations can be simulated, enabling accurate simulation analysis. Properly setting the distribution and mode of action of loads is one of the keys to ensuring the accuracy of simulation results.

# 3. Constraint Setting

Constraints play a crucial role in the simulation process, used to simulate the limiting conditions in actual systems and affect system behavior. In Hypermesh, constraint conditions can be set in the following ways:

#### 3.1 Concept and Role of Constraints
Constraints refer to restrictions or regulations on certain degrees of freedom in a system, which can be restrictions on displacement, force, or other physical quantities. The role of constraints is to ensure that the system complies with actual conditions during simulation, preventing unreasonable motion or deformation.

#### 3.2 How to Set Constraints in Hypermesh
In Hypermesh, constraints can be set through the "Load Collector" panel. Choose the corresponding load type (such as fixed boundary conditions, spring support, etc.), then select the nodes or surfaces on the model where constraints need to be added, and set the appropriate constraint values.
