Good visualizations of computational fluid dynamics (CFD) results are key to making the best use of them. In many cases, CFD results involve multidimensional data embedded in 3D, and it can be difficult to recognize such complicated 3D shapes when they are projected onto 2D displays. A promising alternative approach uses a 3D printer to build real objects representing the CFD results. In this paper, we present a method of 3D printing the isosurfaces of CFD results to visualize them. However, there is a problem that the isosurfaces are not connected. Therefore, to prevent the structure from breaking up, we must find a way to connect them, and we achieve this by using beams to generate a support structure. We take a structural mechanics approach, using an algorithm to optimize the support structure such that the printed object does not break under gravity, enabling us to hold it safely for observation.

使用结构力学进行3D打印CFD模拟结果^☆

良好地可视化计算流体动力学（CFD）结果是充分利用它们的关键。在许多情况下，CFD结果涉及嵌入3D的多维数据，当将这些复杂的3D形状投影到2D显示器上时，可能很难识别它们。一种有前途的替代方法是使用3D打印机构建代表CFD结果的真实对象。在本文中，我们提出了一种3D打印CFD结果的等值面以使其可视化的方法。但是，存在不连接等值面的问题。因此，为防止结构破裂，我们必须找到一种方法将它们连接起来，并通过使用梁生成支撑结构来实现这一目的。我们采用结构力学方法，
