Does VA One SEA use cached data when solving in batch mode?

Does VA One SEA use cached data when solving in batch mode?
Yes. With a .va1 as input to the batch solve, VA One SEA will use the CLF's cached in that .va1 if they exist. However, when passed a .ntf or .xml file VA One SEA solves from scratch each time. read more

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
