new NASTRAN output for the export to FEA software

In connection with iWind, CADWIND V10.3. offers a new function to export the component geometry and laminate data in NASTRAN (NASA STRucture ANalysis) format. The NASTRAN format can be used for various Finite Element Analysis (FEA) software programs such as MSC Nastran, Siemens Simcenter Nastran / NX Nastran, Strand7, etc.

new HDF5 Composite CAE output format for the export to FEA software

CADWIND V10.2 offers a complete new way to export the component geometry and laminate data to Finite Element Analysis (FEA) software: the HDF5 Composite CAE format.

MATERIAL developed the new interface in cooperation with ANSYS. The HDF5 Composite CAE format is also supported by other FEA software manufacturers like Siemens VISTAGY / Fibersim, Altair HyperMesh, etc. Among other things, the HDF5 Composite CAE format allows the analysis of thickwalled components.

iWind

CADWIND V10.1’s main new feature is the new iWind algorithm. iWind is an entirely new way of simulating filament windings. It is rich in new features, all designed to make it faster and easier for the user to find optimal winding patterns and and enhances the CADWIND experience even further.

CADWIND V10.1 gives instant results on the screen as parameters are changed, allowing for fast experimentation. A complete list of possible patterns is displayed from which you can quickly and easily choose the winding that is right for you.

Summary of iWind:

• completely new designed algorithm
• improved friction modelling for better results
• calculates more points with higher precision
• very fast by using the full power of all CPU cores (real parallel processing)
• lists directly a whole range of possible winding patterns
• patterns are shown in an extensive table with all their characteristics
• the pattern list can be sorted, filtered, searched and grouped to quickly find the best patterns
• new types of patterns including patterns with several layers
• optional simulation of the first winding cycle for fast results
• new Live View functionality: instantly visualize windings as parameters change
• all parameters have slider bars, so they can be quickly set by mouse and exactly set by keyboard
• pattern search depth can be set by slider: from "Basic" for speed to "Deep" for all results
• the start position can be changed to help find different winding patterns
• the winding direction can be selected (forward or backward)
• degree of coverage can be set as an acceptable range, only patterns in the range are listed

Project and file management

CADWIND V10.1 has also a new improved project and mandrel file management:

• You can now include the mandrel model data, the output format definition data and comments in the project files. This makes it much easier to manage and document all of your winding projects.
• The mandrel model generator parameters are now written as comments in the MDR files so that the user can directly see the dimensions of the part. Furthermore, the model generator parameters can be saved and loaded for easier use of the mandrel model generator.
