Hi skamajaya,
As I understand it, the DMR file is not being generated in the ‘tempdir’ directory after using ‘fetchOutput’. If the ‘tempdir’ is empty, it might be because the data is being stored in a different directory or directly in memory until you explicitly save it. To debug this, refer to the following steps:
- Check whether the data is being stored in memory or disk with 'Simulink.sdi.getStorageMode()'
- If the data is being stored in memory change it to be stored in disk using 'Simulink.sdi.setStorageMode("disk")'
- If the data is being stored in being stored in disk, check its path through 'Simulink.sdi.getSource()'
- Verify if the generated file is being deleted due to low disk space by using ‘Simulink.sdi.getDeleteRunsOnLowSpace()’
Once you identify the path where the data is stored, you can set your own path for storing data via 'Simulink.sdi.setStorageLocation()'.
You can refer to the following links to know more about various functions dealing with logged data:
