常用的前后处理器有:
1. LS-POST
LSTC自己的后处理软件,现在还是免费的。速度很快,用起来感觉很爽。
2. FEMB
ETA开发的前后处理软件,是迄今为止支持LS-DYNA的功能最全的前后处理。号称不需要手工修改LS-DYNA输入文件。
还开发了其他针对LS-DYNA的前后处理,DYNAFORM是专门模拟板料成形的软件;VPG是做汽车碰撞、道路测试等仿真的软件。
3. Altair/Hypermesh
网格划分功能很强,特别是在汽车业很有名。
4. ANSYS/LS-DYNA
ANSYS开发的针对LS-DYNA的前后处理器,秉承了ANSYS的传统,熟悉ANSYS的用户用起来感觉比较熟悉,特别是可以用APDL编写命令流。但支持LS-DYNA的功能有限,往往需要手工添加keyword,因此习惯了DYNA的keyword的用户不喜欢用它。
5. MSC/Patran
$D"m4?5zA"Yq
MSC的Dytran是从DYNA3D来的,现在跟LS-DYNA是竞争对手。但MSC/Patran还是保留了与LS-DYNA的接口。
其他在国内较少见前后处理:
6. Japanese Research Institute, Ltd - JVISION
.B JVISION is a general purpose pre-post processor for FEM software. Designed to prepare data for, as well as support, various types of analyses, and to facilitate the display of the subsequent results.
7. Oasys, Ltd - Oasys Primer & Oasys D3Plot
Oasys D3Plot is a 3D visualization package for post-processing LS-DYNA analyses using OpenGL?(SGI) graphics.
8. CEI: Ensight and Ensight Gold provides a complete tool for all types of engineering analysis, visualization and communication
EnSight lets you see what you've been unable to display and document in the past. A flexible GUI enables you to learn the program quickly and to move easily into layers of increased functionality. Plus, EnSight works on all major computing platforms and supports interfaces to most major CAE programs and data formats.
