Easy是一款用于膜网和索网结构综合规划和计算的软件。程序系统由 5 个模块组成，用于找形、静态和切割图案生成：

Easy.Form：形状查找是评估受力表面几何形状的过程：只有轻质表面结构才需要它，因为几何形状和物理行为的分离是不可能的。传统结构的几何形状可以由建筑师在绘图板上定义。在Easy.Form中，应力谐波表面将根据用户定义的条件进行配置。

Easy.Stat：静态分析的功能是将Formfinding过程创建的表面具体化（即将材料属性分配给膜），考虑法律规定导致的外部原因（例如自重，风荷载和雪荷载），并计算内部应力和变形：因此可以验证整体结构的稳定性。

Easy.Cut：切割图案生成是一项与地图投影类似的任务。地图投影学说将地球的投影视为平面图。在织物的切割图案生成中，处于平衡状态的三维表面也被投影到一个平面中;在这里，不可避免的像差也应该尽可能小。

Easy.Beam：只有将梁结构与预应力纺织品表面（分别为索网或箔）结合计算，才能保证所有横截面的有效和最佳利用。将静态系统划分为具有非线性行为的轻质表面结构的子系统会得到错误的结果。在Easy.Beam中同时计算整个系统，考虑到了这种情况并优化了资源。

Easy.Vol：气动结构的计算以压力为特征，压力会永久影响表面。该压力必须包含在所有计算中。在找形过程中，它作为形状赋予因素起着决定性的作用。在静态分析中，它与所有其他参数一起是有效的：由于压力可能会在无关原因的情况下发生变化，因此物理气体定律对于精确建模至关重要。

Easy.Wind：由于膜结构的复杂形式和空气动力学行为，在膜结构上产生风荷载可能具有挑战性。这就是数字风洞或计算流体动力学 （CFD） 仿真非常有益的地方。数字风洞利用数值建模和仿真技术来模拟结构周围的空气流动。



Easy.Form: Form finding is a process to evaluate the geometry of a stressed surface: it is only required for lightweight surface structures, because a separation of geometry and physical behavior isn't possible. The geometry of conventional structures can be defined by an architect at the drawing-board. In Easy.Form a stress harmonic surface will be configured under consideration of user-defined conditions.

Easy.Stat | Statics for tensile membrane engineering and textile construction
Easy.Stat: The function of the static analysis is to materialize the surfaces created by the Formfinding process (i.e. to assign material properties to the membrane), to consider the external causes resulting of the statutory provisions (e.g. self-weight, wind and snow loads) and to calculate the inner stresses and deformations: thus the stability of the overall structure can be verified.

Easy.Cut | Patterning
Easy.Cut: The cutting pattern generation is a task which is well known in a similar way from map projection. The map projection doctrine treats the projection of the earth into plane maps. In the cutting pattern generation of fabrics, the three-dimensional surfaces being in equilibrium are also projected into a plane; here too unavoidable aberrations should become as small as possible.

Easy.Beam | Calculation of beam structures together with prestressed textile surfaces
Easy.Beam: Only a combined calculation of beam structures together with prestressed textile surfaces (respectively cable nets or foils) guarantees an efficient and optimal utilization of all cross-sections. The division of static systems into subsystems for lightweight surface structures with non-linear behavior gets wrong results. The simultaneous calculation of the complete system in Easy.Beam makes allowance for this circumstance and optimizes resources.

Easy.Vol | Form finding and statics of pneumatic structures
Easy.Vol: The calculation of pneumatic structures is characterized by pressure which affects the surface permanently. This pressure must be included in all calculations. In the Formfinding process it plays a decisive role as shape giving factor. In the statical analysis it is effective together with all the other parameters: due to the fact that the pressure can change in case of extraneous causes, physical gas laws are essential for exact modeling.


Easy.Wind: The generation of wind loads on membrane structures can be challenging due to the complex forms and aerodynamic behavior of these structures. This is where a digital wind tunnel, or computational fluid dynamics (CFD) simulation, can be highly beneficial. A digital wind tunnel utilizes numerical modeling and simulation techniques to simulate the flow of air around the structure.
