Ansys Rocky Student Add-Ins: Rocky Modules & Scripts

Ansys Rocky Student Add-Ins enhance the Rocky Student Version with specialized modules and scripts that extend its capabilities. These tools allow users to apply external forces, remove particles, modify particle properties, collect data, and achieve much more.

Unlock new possibilities and take your simulations to the next level with these powerful tools.

These modules are specialty models to expand the core solver capabilities. To install a module, download and unzip the file into the “Ready-to-use Module” folder (OS-specific location provided below) and then restart Rocky:

Windows: %USERPROFILE%\Documents\Rocky\Modules

Following module is available under ready-to-use module

 

Type

Name

Description

External Heat

Thermal Radiation

Enables you to add radiation heat exchange between particle-particle interactions that occur during the simulation. Also enables you to set geometries as radiation heat sources for the particles

 

Documentation containing technical and usability details for modules are available in the Rocky Module Manual.

Functional – Code Examples

The functional modules are modules that have been developed to extend Rocky capabilities in a real-case scenario, allowing module users to add external forces, remove particles, modify particle properties, gather data and more.

Following functional module is available in Rocky Student

Basic examples to create your own modules are given below:

The modules that have been created as simple examples of certain Solver SDK functionalities, but currently have no physical or functional meaning. Therefore, these modules should not be considered for usage in a real case. The source code can instead be reviewed as a good example of Solver SDK usage.

Basic examples to create your own modules are given below:

Type

Name

Description

Adhesion Model

Transient Adhesive Force

Enables you to use a Transient Adhesive Force model that will increase over time the adhesive forces between particles and between particles and boundaries. It can be used as an example of Solver SDK usage.

Data Gathering

Contact Curves

Enables Rocky to create additional Contact Frequency and Contact Number curves for both Geometries and Particles. It can be used as an example of Solver SDK usage.

Particle Identification

Spherical Region

Enables you to define a spherical region and then mark particles inside of it for later analysis. It can be used as an example of Solver SDK usage.

Particle Modification

Transient Size Scale

Enables you to use a Transient Size Scale to increase the particle volume and mass over the predefined time interval. It can be used as an example of Solver SDK usage.

Field Force

Field Force

Enables you to specify the name of the Point Cloud that was already defined with an imported force field .txt file, which will then be used as an additional body force acting on particles. It can be used as an example of Solver SDK usage.

Rocky Scripts are a powerful tool in Ansys Rocky software, allowing users to automate and customize their simulation processes such as model configuration, data post-processing, and results analysis.

This script is currently available for use: Setup Basic Rocky Project

Documentation containing technical and usability details for scripts is available in the Rocky Scripts Manual.

An Ansys Rocky Custom Module is a compiled library that attaches to the Rocky solver at strategic points during the simulation, allowing the execution of a custom code.

Your custom module can be written in C++/Cuda and once is ready it can be built with the Rocky Software Development Kit (SDK) and used in your Rocky simulations.

To learn more about how to set up the environments to use the Solver SDK access the Rocky Tutorial 23 on Ansys Help and the Solver SDK Manual on Ansys Developer Portal.
