工业应用案例-风力发电机主机架

风力发电机越大，它的刚度和强度要求就越来越难以满足。重新设计的主机架应该有更好的经济性和振动性能。在同时满足静力和疲劳强度的条件下，主机架的拓扑优化要得到更轻量化的结构，同时还需考虑制造工艺的限制。

最终可行的设计方案中，重量减少了40%，同时也加快了整个开发进程。

TOSCA Fluid工业案例-冷却器进气软管

最新的冷却器进气软管设计要求尽量低的能量损失。在现有设计空间中的重新设计必须满足总的压力降不会减少。

使用TOSCA Fluid进行优化可消除导致能量效率增加的返流和回流区域。新的设计方案同样满足给定的空间限制。只需进行一次求解，比起基于CAD参数化的设计和优化方案节省了大量的计算时间。

SIMULIA TOSCA Fluid 2.4 Linux | 417.8 mb

FE-DESIGN GmbH, a engineering and software company for numerical optimization solutions based on finite element analysis (FEA) and computational fluid dynamics (CFD), announced the release of Tosca Fluid 2.4, is so far the only available system for topology optimization of channel flow problems. Starting from an initial design space, an optimized design of a flow channel is determined automatically by Tosca Fluid. With only one CFD solver run an optimized structure with e.g. significantly reduced pressure drop or homogeneous flow is derived. This allows for the first time an economic topology optimization of industrial large scale flow applicatons.

What new in SIMULIA TOSCA Fluid 2.4:

Supported CFD solver interfaces

- Tosca Fluid supports STAR-CCM+ starting with version 6.04.014. The newest supported solver version is 9.02. Both the single and the double precision variants of STAR-CCM+ are supported. Furthermore the installer now allows the set-up PoD license usage of STAR-CCM+ by adding according options to the solver call.

- Tosca Fluid supports using the Fluent solver versions 13.0 to 15.0.

Refinement of slices near flow boundaries

- A new feature to increase the number of slices along the primary particle tracks near the flow boundaries has been introduced. The usage of the feature can be activated within the graphical user interface. Additionally, a parameter defining the level of refinement is available.

Filtering slices based on particle tracks

- A method for filtering the extracted slices by checking intersections with the primary particle tracks has been added. If a slice along a primary particle track is resulting in multiple closed splines, only the spline enclosing this specific primary particle track is retained. This is especially helpful for an eased CAD reconstruction in case of multiple primary particle tracks when creating a slice for one primary track would result in cutting other primary particle tracks as well.
