For large or finely [discretized|kb:Discretization] models, [influence-based moving-load|kb:Influence-based moving-load analysis] analysis may become time consuming. AWhile this serieslevel of tipsdetail may whichbe aresuitable availablefor tofinal reduceanalysis, computationala time,series andof maytips, bepossibly useful duringto preliminary design, are available to reduce computational time, listed as follows:

* Reduce the number of members for which response is computed by specifying groups smaller than All on the Moving Load Case Results Saved menu (Figure 1), available through Define > Bridge Loads > Bridge Responses _or_ Bridge > Bridge Response.

* Use a coarser [lane|kb:Lane] [discretization|kb:Discretization].

* TheUse option forthe Quick Response Calculation isoption, also available to speed analysis time by usingwhich uses a limited number of [lane-load points|kb:Lane-load point] to approximate the shape of the influence line.
