Inventor Nastran 2020破解版提供跨多种分析类型的广泛模拟。 Inventor Nastran 2020是产品设计和制造系列的一部分 - 在CAD嵌入式工作流程中提供高端仿真，因此工程师和分析师可以做出明智的设计决策。Autodesk Inventor Nastran使用两个文件进行输入定义：模型初始化文件和模型输入文件。模型初始化文件将Autodesk Inventor Nastran配置为在您的系统上运行。它允许您指定输入文件的位置，数据库和输出文件的放置位置，输出文件的格式，使用的内存量和内存类型，以及如何控制程序执行。模型输入文件通过指定结构的几何，材料属性，边界条件和载荷来描述模型。某些实体（例如模型参数）对两个文件都是通用的。

Inventor Nastran 2020新功能介绍

Mesh convergence

Set convergence criteria for entities to specify the result type and maximum number of refinements to reach convergence.

Global (left) and Local (right) mesh convergence results

For more information, see Mesh Convergence.

Hydrostatic load

This new load type enables you to analyze hydrostatic fluid pressure that varies with the depth of fluid in a particular direction. Pressure is always normal to an element face.

For more information, see Hydrostatic Load, and the Flat Walled Tank Exercise, which has been revised to demonstrate a hydrostatic load.

Vault project management

Autodesk Inventor Nastran can use Vault as a convenient way to store and manage project results. When Inventor and Vault are both installed on a computer or network, the Vault tab appears in Inventor.

The parts for a project must be stored in a Vault project folder, and then opened in Inventor for analysis. Inventor Nastran analysis results are stored in a PKG file, inside a '3rd Party' folder for each part on the Inventor Model Tree, as shown above. Anyone opening the part or assembly in Inventor Nastran can load the analysis results from the Results node on the Analysis tree:

The Vault PKG file can be updated by right-clicking the Analysis node on the Nastran Model Tree:

Expanded Constraints selection

The Constraints section of the Inventor Nastran ribbon provides direct access to Pin and Frictionless constraint types.

Units system standardization

Inventor Nastran now uses one consistent units system for the ribbon bar, Analysis Tree, and Model Tree. In previous releases, the ribbon bar and Model Tree used the units defined with the model.

Shell element options correction

The input for shell elements has been corrected. Instead of entering a Bottom Fiber Distance, users now enter a MidPlane Offset Distance. This has two consequences for existing models in which the Bottom Fiber Distance was entered:

The previous analysis did not use the Bottom Fiber Distance correctly when creating the Nastran file. Therefore, the results are for a different arrangement than intended.
Before running an existing model with the current software, the input for MidPlane Offset Distance needs to be corrected.

New iLogic commands

Commands are now available to create or delete a new analysis and a new subcase.

Improved frame generator handling

Saving an Inventor Frame Generator model now takes much less time in the Inventor Nastran environment. An issue with solids not being hidden properly has also been resolved, and the new version avoids the improper selection of sketch entities.

Renamed material tables

The tables for Young's Modulus vs. Temperature and Thermal Conductivity vs. Temperature have been replaced with a Load Scale Factor vs. Temperature table. Load scale factor is a multiplier to Young's modulus and thermal conductivity.
