To-do-list based on observations in April basin slot | Status |
---|---|
Inspect agent messages to trace the set XMF states by the basin | Incorrect sequence of the set state in XMF state machine by the facility |
Inspect main sheet control to avoid an initial value of 0, which might be caused by the embedded GUI. | Initial length added and length is a dimensionless value between 0 and 1. |
Create a tagged version of the XMF configuration files, which were used in the April slot. | Version 1.0.0 was created. |
Root cause analysis of the missing logged samples at t=0.1s. | Incorrect sequence of the set state in XMF state machine by the facility |
Doubts about meaning of set integer for status value by agent (0,1,2), info only. | Minor issue and ignored for now. |
Write a MIL procedure to check your XMF model behavior after enabling the re-initialize state. |
Version 2023.02.1 of xSimulation must be used.

Checked October 13th 2023 in the OO&S lab with xSimulation 2023.02.2 | |
Add line tension (true/false) to the state | Skipped, due to issues to retrieve proper values for both the XMF physics and basin set-up |
Add reward optionally to the the com node | Skipped |
Include change rate settings for all three actuators | Property references are now included for all three actuators. |

The xmf
directory contains a number of directories, which are listed in the figure below.
The _info
directory contains all available background information, which was used to set-up the numerical XMF model. This information consists for example of papers, script, drawings and CAD files.
...
A dedicated main.xmf
file is available for each mode. Accordingly, XMF nodes can be included/excluded and enabled/disabled to obtain the required behavior of the mode. If the basin is not included, a physics model in XMF will be used to model the Optimist's behavior. When the basin controls XMF, the Optimist's state from the basin is directly set to the bodies and actuators in XMF. With this solution the interface between XMF and the RL-agent remains intact. There is no intrusive behavior on this interface once the basin is included.
...
The main.xmf
files supporting the four modes are located in directories of the xmf/general/mode
directory as displayed below.
The main.xmf
file is called by an input.xmf
file. The input.xmf
file is extended with property references, which are favorable for the preferred mode. These property references can be set on the command line or selected in the basin by means of the MIL-GUI (Model-In-the-Loop Graphical User Interface). This GUI is generic and only supports the coupling between the basin and XMF. The input.xmf
files are saved in the run
directory as displayed in the snapshot below. The agreed conventions of the MIL coupling between the basin and XMF are followed.
The mil_benchmarks
directory contains the basic checks (benchmarks), which are executed in the basin prior to any MIL project. The test matrix for the MIL application in the basin are saved in mil_testMatrix
directory and displayed below. In total six tests are available, which are a combination of two (2) modes and three (3) wind velocity settings (0%, 40% and 60%). The selected wind velocity should match with the applicable wind setting in the basin. If this is not the case, incorrect apparent wind velocities and headings are recorded by the anemometer in the XMF model and transferred to the RL-Agent.
The input.xmf
files of the other modes (gui
and agent
) are saved in the mil_none
directory. Properties are typically set on the command line.
