No tool is a silver bullet. Lightning protection calculation software has inherent constraints:

Computational Methods in Lightning Protection System Design: A Critical Analysis of Modern Calculation Software lightning protection calculation software

Software engines simultaneously evaluate four distinct risk vectors: direct structural impacts ( RAcap R sub cap A ), physical near-miss fire hazards ( RBcap R sub cap B ), internal system electronic failures ( RCcap R sub cap C ), and incoming utility service line failures ( RDcap R sub cap D 2.

Traditional lightning protection design followed prescriptive standards like (international) or NFPA 780 (US). A designer would manually measure a structure’s dimensions, calculate its equivalent collection area, estimate the number of lightning flashes per square kilometer per year (Ng), and then determine risk components (loss of human life, economic loss, cultural heritage damage). They account for: While RSM is standard, it

Advanced modules analyze the grounding grid. They solve the Laplace equation to map the Ground Potential Rise (GPR) and ensure touch/step voltage limits are not exceeded. They account for:

While RSM is standard, it is conservative. Software strictly adhering to RSM often suggests more air terminals than necessary for complex, recessed architectural features. Conversely, CVM-based software offers better optimization but is not universally accepted by all local building codes (e.g., some jurisdictions strictly mandate RSM).
