Define and implement a framework for component quantity unit handling

[zsarnoczay]

Problem

• Mismatched units between CMP_QNT and downstream expectations can distort damage and repair metrics. Pelicun allows a wide range of units and outputs damage quantities in whatever the user specifies. ATC 138 code cannot handle arbitrary units and might be based on the blocks defined in FEMA P-58 acting as units (e.g., 100LF).

Proposed solution

• Discuss the requirements for ATC 138 simulation. Document these explicitly and include Unit checks in the Pelicun output converter that warn users if they do not have the right units. Additionally, consider including more flexibility by converting units in the main code; or enhancing the pelicun conversion method to support multiple units at least from Pelicun.
