RC 0.9.9 released

A new version: Release Candidate 0.9.9 was released yesterday. This is a bug-fix update only - it resolves an issue found in some computers (believed to be only those with nVidia graphics cards, but not all nVidia machines are affected) where the saved animations were incorrect, displaying a jumpy motion. If you have the previous version (0.9.8) and saved animation files work correctly there is no need to upgrade to this one.

RC 0.9.8 released

A new version: Release Candidate 0.9.8 has been released today. This is mainly about extra features but also includes some minor bug-fixes. This will probably be the last "pre-release" version, so whether you're interested in the new features or just want to help me verify that all is working correctly, please download and test it!

New: Animated "screen dump" of 3D model window.

As mentioned earlier, the new version includes the facility to export the 3D graphic display as an image or animation.


Stepped sonotrode - 2nd axial mode

3D Image screen capture and export available in version 0.9.8

These example images were generated using the new export facilities included in version 0.9.8 (to be released shortly):

User-defined sonotrode, first bending mode at 7.0 kHz

User-defined sonotrode - first bending mode at 7.0kHz

User-defined sonotrode - second bending mode at 21.47 kHz

Rectangular-section sonotrodes

I've had a couple of emails from people interested in analysing rectangular sonotrodes (eg. for plastic welding). It's something that's already on the longer-term ToDo list but with enough interest I may try to get this out sooner rather than later.

If you're interested, please leave a comment here or contact me via the PowerUltrasonics website.

RC 0.9.7 released

A new version: Release Candidate 0.9.7 has been released today. This contains several bug-fixes and additional features so an immediate upgrade is highly recommended.

New: "Plus-range" models

The database-backed analysis models are limited to the original range of dimensions and material properties. These ranges were a compromise choice - to cover the majority of sonotrode designs in use while limiting the database to a reasonable size (and likewise limiting the computational power required to generate it). However, some clients have found the standard range a bit too limiting, eg. when analysing sonotrodes made from exotic materials whose sound velocity is so low that it falls outside the standard range. I've therefore introduced four new "plus range" models, corresponding to the original stepped-sonotrode, tube, ring and user-defined sonotrode but allowing a wider range of material properties and also dimensions. Regenerating the databases for these ranges is not practical so these new models are only for online-FEA, that is, finite element analysis run on the analysis server on-demand.

New: animated gif image download and save

As the first step of a longer-term project to extract more information from the finite-element analysis running on the remote analysis-server, I've added the option to download animated .gif images of the deformation mode generated by the postprocessor CGX. These open as additional image tabs in the right-side of the SonoAnalyzer program window.

FEA (CalculiX cgx) animated model (second axial mode)

FEA (CalculiX cgx) animated model (second axial mode)

Caution: While the main "Model" graphics window will update to reflect changes in dimensions or model-type, these downloaded .gif images are snapshots of a single design. You may wish to save them to individual files using filenames that describe the dimensions, material etc.

Modified: File menu layout

The file menu has been rearranged to allow for the changes above, placing the new options in a new "FEA" submenu.

Modified: Persistent units selection

As requested, your chosen units (SI, metric or imperial) will now be retained through a program restart. Note that this applies only to the main menu selection, not to any changes made on individual dimensions.

Bug fix:

Fixed jumbled / unusable materials tab after loading model with custom material.

Installation / Upgrade

New buyers will get the new version automatically but if you've purchased an earlier version please log into your account and download the setup file again. I recommend uninstalling the previous version before installing each new version.

Only version 0.9.7 and above is compatible with the new models and image downloads described above.

Persistent units selection

I've had a request for the user's unit selection (Metric / Imperial / SI) to be persistent, ie. to remain unchanged after a program restart. This will be included in the next release.

RC 0.9.6 released

A new version: Release Candidate 0.9.6 has been released today. This contains several minor bug-fixes plus support for the new User-defined Axial mode sonotrode. New buyers will get the new version automatically but if you've purchased an earlier version please log into your account and download the setup file again. I recommend uninstalling the previous version before installing each new version.
