Using pinned/simply supported BC in FE to compare to SEA

Using pinned/simply supported BC in FE to compare to SEA
Why do I need to use pinned/simply supported BC in FE to compare to SEA?, Most, if not all, SEA theory is developed using an assumption of simply supported plates ... read more

How can I move a VA One model backwards in versions using xml?

How can I move a VA One model backwards in versions using xml?
Possible solutions: A workaround is to copy/paste in the 3D window, which will work in many cases. Copy and Paste will work - it just depends on what you are Copy and Pasting... read more

How can I reduce the size of the modal data imported in a hybrid model?

How can I reduce the size of the modal data imported in a hybrid model?
The model will always contain enough data to solve, and give basic results. For models with hybrid area junctions, nodal data for all wetted faces will be generated/recovered which results in much data. read more

Can I set 'none' as the trim when using pi_fPlateGetTrimTL?

Can I set 'none' as the trim when using pi_fPlateGetTrimTL?
No, you cannot set the TRIM parameter to null using the call .You would have to use another approach of plotting the effective TL (Results>Effective Transmission Loss) instead. Below is a short snippet of how to do this. read more

How can I avoid Out of memory for large hybrid area junctions?

How can I avoid Out of memory for large hybrid area junctions?
The problem is due to an FE area junction being too large for the full solve. read more

When would I use a General Laminate (GL) instead of the new (2014.5) sandwich model?

When would I use a General Laminate (GL) instead of the new (2014.5) sandwich model?
One example is for a thick section where the skins are different; in the sandwich model the skins are always the same. read more

Is the coloring correct for an BSR clearance contour?

Is the coloring correct for an BSR clearance contour?
Is the coloring correct for an BSR clearance contour? Yes, this is by design, as higher to low values are always plotted red to blue. read more

Solving X resonant modes with identical natural frequencies gives unexpected results - why?

Solving X resonant modes with identical natural frequencies gives unexpected results - why?
The case of a model with exactly identical natural frequencies is causing the "x resonant modes around center frequency" routine to get confused. A few things that can be done: read more
