The tab Deflections is only available when the modules "Concrete link FEM plate" (282), "Concrete deflections FEM" (296) – is part of the license, material concrete is defined and characteristic /frequent and quasipermanent load combination is present. Also Advanced analysis should be performed with the Assumption "FNL" set on true as well as proper settings in "Analysis Options" for "SLS Analysis method" <NL analysis>.
Value 
Description 
Envelope + / Envelope  dropdown items are representing redistribution of deflection envelops respectively positive and negative direction of Z axis 

w_{max} 
Design value of the remaining total deflection in Z (Z’)direction, with taking in to account precamber w_{max} = (W_{1}+ W_{2}+ W_{3})  W_{c} [mm] 
(W_{2} + W_{3}) 
Design value of a variation of the deflections in Z (Z’)direction due to variable loading + time dependent deformations due to permanent load during the exploitation of the building (W_{2} + W_{3}) [mm] 
Deflection check according EN, NENEN, NBNEN 1990 is satisfying requirements described by EN, NENEN, NBNEN 1990 # A1.4.3.
Calculation presumptions presets are defined using Analysis settings as:
Calculating of concrete deflections using "Short & long term" sigmaepsilon diagram option implies definition rare and quasipermanent combinations are taking in to account influence of creep effects.
These effect on common result values are shown in Results tab by choosing load combinations dropdown items respectively for:

All the deflections specific values doing some influence in to deflections w_{max} (u;add/u;end) or (W_{2} + W_{3}) calculation for some separate finite element, are shown in the tab Deflections. By choose the variable action described loading combination, for example Ch.C.2 or Fr.C. 2, corresponding w_{max} (u;add/u;end) or (W_{2} + W_{3}) chart is represented:
Using the tooltip by pointing an finite element via mouse and pressing right mouse button the components of w_{max} (u;add/u;end) or (W_{2} + W_{3}) calculation is represented:
Dropdown selection Qu.C. 1[Sh.T.] is represented w_{max} (u;add/u;end) or (W_{2} + W_{3}), where the W_{3} component is calculated using Qu.C. 1[Sh.T.] loading combination presets.
Deflections calculation process is ruled by nonlinear processing which calculation options are described in "Analysis settings" tab as:
Default "Automatic" iteration method in based on minimal quantity of iterations is ensure convergence of the solution by using minimal calculation time.
Changing of iteration method in to the "Linear" by manipulating with the number of increments is possible to make investigation to get some better convergence using more increment steps v.s. calculation time.
Nonlinear calculation of deflections is default (SLS:Analysis method <NL analysis>). By choosing of linear calculation of deflections (SLS:Analysis method <Linear elastic>) would be not possible creep effects satisfying requirements described by EN, NENEN, NBNEN 1990#A1.4.3.
Calculation assumptions:
Deflection check with the applied As;prov=As;req(ULS) is done based on the FNL results, while As;req(ULS) is calculated based on linear analysis results. Because of the force redistribution during FNL analysis, applied As;prov sometimes can not ensure bearing capacity of the plate, as then the destruction of the structure appears. For example, after redistribution of forces, the tension force can appear in the element(s), where As;prov isn't applied at all, because As;prov = As;req is applied based on LE analysis. So, such an element is completely destroyed (may be on 0.1 of the total loading) and the calculation is stopped.
