声学的新定向图
新的方向性图类型允许音频工程师描述扬声器的空间响应，这是频率和角度的函数。该图在分析扬声器和其他电声传感器方面很重要。以这种方式代表空间响应在扬声器行业中非常普遍，并且经常以相同的方式表示测得的数据。该图包括许多格式选项，以实现对建模数据的最大见解。一些关键格式功能是：
- Normalization: The input sound pressure level data can be normalized either with respect to a specific polar angle, with respect to the maximal value (at each frequency), or with no normalization.
- Evaluation: The evaluation circle can be defined at any location in space and it is possible to define a reference direction that sets the 0-degree direction.
- Coloring and Style: Format the data as filled surfaces, lines, and add labels. It is also simple to switch the layout of the axis and have the frequency on either theX- 或者y-axis.
方向性图的一个示例，其中数据相对于30度进行了归一化，频率位于X- 轴和标签已添加到图中（左）。相同的数据归一化已在0度下应用，并且频率在y-axis (right)

LaTeX Formatting and Other Improvements to Titles and Annotations
You can now include annotations for 1D plots. This option is already available for 2D and 3D plots in earlier versions of COMSOL Multiphysics®。
In addition, the annotation functionality has been expanded and includes annotations in plot titles and annotations with background colors, frames, and LaTeX markup. Line breaks are now available by using the LaTeX markup option together with special character syntax: \\.
To create the annotation used in the image below, for example, use the text expression:$\sigma_{\textrm{max}}$ = eval(maxop1(solid.mises),MPa) MPa

填充的轮廓传奇
这Contour and Isosurface plot types now include an option for using a filled legend. This functionality is especially useful for filled contour plots.

VTK Export
这Data and Plot export features now support the export of unstructured VTK files (.vtu). This file format allows third-party programs to use this data for visualization.
导出数据或图列出的文件格式列表现在包括非结构化VTK文件格式选项。
派生值中的多个表达式
数值评估功能现在可以一次评估多个表达式。这节省了更复杂模型的时间，因为您不再需要添加一个Evaluation Feature节点每个表达式。
更灵活的桌面图
这Table Surface plot now supports discrete, or staircase-shaped, plots. Additionally, you can create a Table Surface plot from data that has been imported from a file using one of three formats: Filled table, Columns, or Cells. The Filled table option corresponds to the functionality of earlier versions. The new Columns option supports data on a column-oriented format. For example, an imported file corresponds to data saved on the format x,y,z,T, with x,y,z coordinates in the first three columns and a field variable such as temperature in the fourth column. The new Cells option can be used to import discrete data on a matrix format, such as resistance, capacitance, or inductance matrices.

Material Smoothing
Many plot types have a Quality section where you can select a plot resolution, enforce continuity, and specify the use of derivative recovery. In COMSOL Multiphysics®版本5.2a，这些设置已通过几种新选项进行了扩展。对于平滑，您现在有五个选择：
- None
- 内部物质域
- 内部几何域
- 到处
- Expression
新的内部物质域选项对平滑方面的所有域具有与同一区域相同的材料的所有域，但使材料界面的不连续性保持不连续。这Expression选择可用于自定义用于平滑的连接区域，该区域在给定表达式恒定的区域内应用。一个新平滑阈值option makes it possible to consider values that do not differ significantly from each other as having the same value with respect to smoothing. If two adjacent points have different values, then smoothing is performed only if the relative difference between their values is, at most, the given threshold value.

材料域变量
一个新variable,材料，可用于自定义物理设置以及结果中的表达式。该材料变量是一个指标变量，其整个域具有相同材料属性的整数值。关于边界，边缘和点的材料定义的变量，也可以作为材料，，，，material.edge， 和material.point， 分别。变量材料is available at all entity levels: domain, boundary, edge, and point, and inherits any discontinuity from the domain level down to lower dimensional entities.

Use of Parameters for Results
一个新参数现在可以将节点作为子节点添加到Results。可以在后处理和可视化中添加，编辑并用作这些新类型的参数，而无需重新计算模型。例如，一个基于结果参数创建动画的新选项使您可以使用此类参数来对切片绘图的位置，等音表级别或剪切平面数据集的位置进行动画。

Use of Global Expressions for Slice, Arrow, and Cut Plane Positions
现在，您可以使用全球定义的表达式来指定图的坐标。例如，您可以让切割平面的坐标由场变量的最大位置确定。此功能也可用于切片，箭头，切割线等的定位。
