LMS Virtual.Lab Designer (or any CAE Software Suite)… is not a “black box” with immediate and completely accurate design solutions cannot and indeed shoud not be used to obtain “exact” and “absolute” results is no substitute for technical skills, experience, and education is absolutely not a substutite for rigourous testing in all cases requires user attention and responsibility while building models and analyzing results
