FEMtools™ 3.0 Release Notes
FEMtools 3.0 brings many new features in all modules, and enhancements of
existing ones. Following is a overview of the highlights in this release. For
full details, FEMtools users should refer to the Release Notes.
Installation and Configuration
-
FEMtools Pretest Analysis and FEMtools SDM are now available
as separate products.
-
FEMtools Framework and FEMtools Pretest Analysis can be
configured with or without solvers.
-
FEMtools SDM, FEMtools Correlation Analysis and FEMtools Model
Updating now always include the FEMtools FEA solvers.
-
FEMtools Model Updating includes a new tool for probabilistic
analysis.
Documentation
- 1600+ pages of revised and expanded documentation - The FEMtools
documentation has been updated to contain all changes made to the current
release.
User Interface
-
Support of multiple, customizable and dockable/floating
toolbars.
