Thanks, IR. That page did have a Join Group button, which morphed into a Leave Group button after I clicked upon it.
I do not yet actually have write-access to the site of course. This hopefully follows once the box is examined for any black balls.

There is a question that has been bugging me since the recent new-format Eng-Tips landed on me with an unexpected THUMP. Under the old Eng-Tips, we could include a non-breaking space in our text using "[ ]". Under the new system that text string is uninterpreted, and appears as its raw...
I struck this message for the first time a couple of days ago, trying to contribute a question to the Engineering Language/Grammar Skills forum. How does one "engineer" an invitation to such a forum?
Apparently I have "insufficient privileges" to participate in the Language/Grammar forum. I can think of some language to describe that state of affairs, but it might be a bit ungrammatical.
This forum might be able to answer a question that has been bugging me since the recent new-format Eng-Tips landed on us with an unexpected THUMP. Under the old system, we could include a non-breaking space in our text using "[ ]". Under the new system that text string in uninterpreted...
Thanks, Greg. Dramatically informative material.
[My website (https:/rmniall.com) has a spreadsheet for two-degree-of-freedom dynamic systems, which includes a facility for sensitivity analysis. But nothing comparable to what you have presented.]
I have never used PATRAN, and I am probably misunderstanding your question, but ...
If ALL your translations are fixed, your axially directed load "never reaches" your column because it goes directly into the support: you need to release that axial restraint.
I suspect that at this stage the simplest and quickest way for you to obtain the scale-equalising VBA code is for you to extract it from one of the downloadable spreadsheets on my website.

I put just one FAQ up on the old site, quite a few years ago. It was basically a wad of Excel VBA code to ensure that an "X Y (scatter)" chart would have equal X and Y scales, which enabled Excel's charting capabilities to be used to produce undistorted shapes on spreadsheet pages. The code came...
This intra-thread referencing is now quite a pain in the RRRs, and I have already raised it in another forum.

I can vaguely remember being involved in a discussion on this general question, more than several decades ago. It concerned the appropriate load factor to be applied to the design of some short-term works that would provide access for repair workers to get to the places in need of repair. Most...
With the old Eng-Tips, all times generated by "the system" were displayed in UTC. Now (I think) they are all displayed in the viewer's time-zone. This has some advantages, but it also has some disadvantages. In an active thread, some contributors can have a large number of different posts...
I agree with ALK2415. The site makes excessive use of faint font.
To which I would add that the site's various pages have acres (even hectares) of totally unnecessary white space. Can this be lessened. Not everybody likes to give their mouse a good run in the morning.
rb1957.[ ] You may well be right about the potential significance of shear deformations in the beam, but the only way I can think of to investigate that would be modelling the beam using a large number of three-dimensional cuboid-shaped elements.[ ] This would be megaparsecs beyond...
sorry, Greg. One of the limitations in the Strand7 demo version is (¡was!) that it does not have any way of saving any aspect of a model. When you close the program everything evaporates instantly.

Unfortunately I had a hardware problem almost immediately after my Strand7 run, and ended up corrupting the software. Then I discovered that the company no longer offers a "demo version". So further analyses are impossible.

To sort this out in my own mind I followed SWComposite's 09Oct24@21:03 suggestion and resorted to the Strand7™ software.[ ] I set up a simple horizontal beam as follows.
» No units (all data to use internally consistent units).
» Overall length 20, comprising 20 end-to-end beamlets each...
Equilibrium![ ] Consider that roller end.[ ] It has just one external force acting on it:[ ] the reaction, which is vertical.[ ] It has two internal forces acting on it:[ ] the beam's end axial force (parallel to the beam's INCLINED centreline), and the beam's end...
