September 2013 - DDS Releases FEMtools 3.7

Dynamic Design Solutions announces the release of FEMtools 3.7. The new version is available for download from September 2.

FEMtools 3.7 is a major revision of the FEMtools software suite that introduces new dynamic analysis and substructuring features (dynamic compensation, modal-based assembly), as well as improvements to FRF-based assembly, pretest analysis, correlation analysis and model updating. There are also various improvements and extensions to the interface programs, commands and API functions.

The highlights of this new release are summarized hereafter:

  • Computation of Frequency Response Functions (FRFs) is improved in the following ways:
    • The modal method can now be enhanced by using the Dynamic Compensation method.
    • The Padé Method for direct FRF computation now includes automatic convergence control.
    • Direct FRF computation now supports features like multi-reference enforced displacements and local coordinate systems.
  • Modal-Based Assembly (MBA) is added as a new dynamic substructuring method that can predict the impact of a modification on the dynamic properties of a structure. The MBA implementation in FEMtools 3.7 supports FEA data, test data or a combination of FEA and test data (hybrid modeling). MBA is an extension of Structural Dynamics Modification (SDM) and replaces the SDM tool that was included in previous FEMtools versions.
  • FRF-Based Assembly (FBA) was introduced in a previous release but is further extended in FEMtools 3.7. FBA loads and responses are introduced which enable the FBA module to perform Transfer Path Analysis (TPA). FBA now also supports multi-point constraints, computation of the internal forces in the FBA connection points and the use of enforced displacements. Additional examples that illustrate the applications of FBA have been added.
  • Pretest analysis now uses uniform GUI panels that offer the same level of integration and functionality for all sensor selection methods. This includes the possibility to use fixed sensor locations, and preview of the candidate locations based on minimal sensor selection among other new features.
  • Correlation analysis introduces a new spatial correlation algorithm for processing large data sets like the point clouds obtained with non-contact sensors (laser scanning vibrometers). Directional node-point pairing and multi-step node-point pairing are added. Mode shape pairing can now be based on POC and mode pairing for axisymmetric structures has been improved.
  • Model updating can now use a new method for automatically improving the condition of the Bayesian updating equations. This results in a more robust updating process for cases with a high number of updating parameters or updating responses. FEMtools 3.7 also offers additional flexibility for rejecting updating results. Several improvements have been made to text-based parameter updating and multi-model updating. Generic responses can now be used for a more flexible approach to model updating in case of non-standard responses.
  • Extended scripting functionality is offered through 27 new commands to be used in command scripts. FEMtools Script programmers will benefit from new utility and FEMtools API functions.
  • The FEMtools database and project files (fdb, fpj) are now saved in compressed format resulting in smaller data files.
  • The principle FE data interfaces and solver drivers (Abaqus, Ansys and Nastran) have been upgraded. For example, the Abaqus and Ansys interfaces now support importing FRF data, and the Nastran driver can now pilot the MSC.Nastran ACMS solver.
  • The flexibility of the Universal File Format interface has been improved and settings can now be controlled with a settings dialog box.
  • The Polytec file interface has been rewritten to improve performance and robustness.

FEMtools 3.7 is available on Windows and Linux as a free upgrade for all customers with current maintenance and technical support contract. Availability of the version for Mac OS X will follow at a later time and will be announced at this location.

If you have a current Maintenance and Support contract and did not yet receive a login name and password, then register at http://www.femtools.com/support.htm or send a request to licensing@femtools.com.

Time-locked license files (annual) for FEMtools 3.4-3.6 remain valid for v3.7.
License files without expiration date issued for a previous version are not compatible with FEMtools 3.7 and will need to be replaced.

March 2013 - IMAC Display of Shaking Race Car

California-based FEMtools distributor NAVCON did some "shakin" of a Porsche 911 race car at the 31st annual International Modal Analysis Conference (IMAC) that was held last February in Anaheim, Los Angeles. 

The car was instrumented with PCB transducers and excited using a long stroke APS Dynamics shaker. Frequency response measurements were made in the exposition area using a Data Physics Mobilyzer. The data was used for modal parameter extraction and subsequent finite element model validation.
