Given the complexity of building behavior, it makes sense to use existing simulation tools rather than to carry out all calculations from scratch.
There are quite a few criteria to consider when choosing a simulation tool: <ul class="circleList"> <li>Accuracy</li> <li>Validation</li> <li>Documentation</li> <li>Familiarity</li> <li>Interoperability </li> </ul> Although there may be a strategic aspect to the question, it is important to consider the issues to be addressed by simulation on a case-by-case basis.
