Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
SolidWorks (stylized as SOLIDWORKS) is a brand within Dassault Systèmes that develops and markets software for solid modeling computer-aided design (CAD), computer-aided engineering (CAE), 3D CAD design, collaboration, analysis, and product data management. [2] The company introduced one of the first 3D CAD applications designed to run on a ...

graph with an example of steps in a failure mode and effects analysis. Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects.
The different parts of Elmer software may be used independently. Whilst the main module is the ElmerSolver tool, which includes many sophisticated features for physical model solving, the additional components are required to create a full workflow. For pre- and post-processing other tools, such as Paraview can be used to visualise the output.
Fault reporting is a maintenance concept that increases operational availability and that reduces operating cost by three mechanisms: Reduce labor-intensive diagnostic evaluation; Eliminate diagnostic testing down-time; Provide notification to management for degraded operation; That is a prerequisite for condition-based maintenance.

No fault found (NFF), no trouble found (NTF) or no defect found (NDF) are terms used in the field of maintenance, where a unit is removed from service following a complaint of a perceived fault by operators or an alarm from its BIT (built-in test) equipment. The unit is then checked, but no anomaly is detected by the maintainer.
