Dynamic Analysis: Modal superpos. or Direct Int.
Dynamic Analysis: Modal superpos. or Direct Int.
(OP)
In the field I am in (structural) mode superposition is commonly used to perform dynamic analyzes. Is this a default analysis method also for other fields, e.g. automotive, mechanical,...?
Of course, direct integration is more accurate but is the accuracy of a modal superposition generally sufficient?
Regards,
Andreas
