New VA One 2014.5 variables

Which are the new variables introduced in VA One 2014.5? VAONE_USE_PARDISO_SOLVER=1 VAONE_LJ_ANGLE_FIX VAONE_LJ_HERMITIAN_FIX VAONE_REPORT_LJ_ANGLE_FIX

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.

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 ...

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...

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.

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.

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.

Create FE subsystems from a PIDs

How do I create FE subsystems from a PIDs??? Below is an example to:

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.
