This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.
The PAS is an expandable multi-channel (up to 36 channels) system that consists of the Pulser Amplifier Desktop units (PADs) and Pulser Interface Unit (PIU).
The PAS provides pre-amplification and switching between pulsing and receiving mode for all transducers in a multi-sensor array during an ultrasonic survey.
Each PAD has selectable gains between 30 and 70 dB, and a broad frequency response with a plug-in filter circuit to tailor the unit to the desired frequency range. The unit is software controlled over the PC USB interface.
