Amplitude

Amplitude settings define the variation of applied loads, body forces or boundary conditions over time. They are critical for simulations involving static, dynamic or transient analyses, allowing users to specify how forces, displacements, or other parameters change during the simulation.

Amplitude Types

Ramp

Linearly increases or decreases the load over time.
Suitable for gradual load applications to avoid sudden impacts.

Rising Sin

Represents a sine wave that rises in amplitude.
Commonly used in dynamic simulations where smooth oscillatory loading is required.

Rising Cos

Represents a cosine wave with increasing amplitude.
Similar applications as Rising Sin but starts from a maximum value.

Periodic

Creates a cyclic, repeating amplitude pattern.
Useful for simulations involving cyclic loading or vibrations.

Equally Spaced

Defines amplitude based on equally spaced time intervals.
Provides flexibility for custom non-linear variations.

Tabular

Allows users to input custom amplitude values directly in a table format.
Ideal for simulations with complex, non-standard amplitude variations.

User Defined

Enables users to programmatically define amplitude using a script.

How to Configure Amplitude

Select the Amplitude option from the tree.
Choose the desired amplitude type from the dropdown menu.
Configure parameters as needed (e.g., intervals for equally spaced or values for tabular).
Once defined, the amplitude is saved for later use and can be assigned to loads or boundary conditions during their configuration, ensuring consistent and accurate application throughout the simulation.
