Algorithm (Workflow)
This function, smbCreateSineWave, is designed to create a cosine wave as a Simulink signal. It is part of the SG-Library and was introduced in SolidGeometry 3.1. Below is a detailed explanation of the algorithm and its parameters.
Input Parameters
- SName: The name of the generator. The default value is 'Sine Wave'.
- EPort: An optional port to connect. If not specified, it remains empty.
- amp: The amplitude of the sine wave. The default value is À (pi).
Algorithm Steps
- Initialize the default values for
SName, EPort, and amp.
- Check if any input arguments are provided and update the default values accordingly.
- Use the function
smbAddBlock to add a 'Sine Wave' block to the current Simulink model (gcs).
- Set the position of the current block (
gcb) using smbSetPosition and smbNewGridPos.
- Configure the block parameters:
- Set the phase to À/2 to ensure no force during singularity.
- Set the amplitude using the provided or default value of
amp.
- If
EPort is not empty:
- Extract the subsystem name from
EPort.
- Use
smbWhich to determine the subsystem.
- Retrieve the ports using
smbGetPorts.
- If there are existing connections, delete them using
delete_line.
- Add a new line connecting the 'Sine Wave' block to the specified
EPort with autorouting enabled.
