PrePoMax – 开源CAE软件

PrePoMax 是 Calculix FEM 求解器的开源预处理器和后处理器，基于现代用户界面，可加快 FEM 工作流程。

CAD 几何支持
PrePoMax 允许您从各种可交换的 CAD 格式和用于 3D 打印的立体光刻 .stl 文件中导入几何体。CAD 支持基于开源 Open Cascade 平台。

实体和壳体几何网格划分
PrePoMax 允许您使用线性和抛物线有限元对实体或基于壳的几何体进行网格划分。它还支持从文件导入有限元网格。开源 Netgen 库执行网格划分。从 2.0.0 版本开始，集成了 Gmsh 网格划分器，支持六面体和五面体网格划分。

几何和基于网格的特征定义
PrePoMax 允许您根据几何或有限元网格选择创建各种 FEM 特征所需的节点集、单元集和曲面。

结果可视化
PrePoMax 允许您使用带有动画的 3D 标量场和使用 2D 绘图工具来表示历史输出来可视化结果。

PrePoMax is an open-source pre and post-processor for the Calculix FEM solver based on a modern user interface to speed up the FEM workflow.

PrePoMax contains many features needed to prepare, solve and post-process different FEM models. An overview of the most important features is listed below.
