Z88-Forum

Well… maybe not quite. How about five more minutes to learn all there is about node entry in Zak? you might want to open this in another tab or window. Its wider than the Z88 frame. http://screencast.com/t/aO3oQSJap2k Shows: • Creating a new model • Opening the ModelBuilder • Data entry via the numb...

Five minutes of your life to see what Zak offers. you might want to open this in another tab or window. Its wider than the Z88 frame. http://screencast.com/t/4ArRjh9je Shows: • a completed model • moving around the model • most of the buttons • ModelBuilder description and purpose • successful expor...

http://z88.garmf.com/Zak/Zak128.png I don’t know about other engineers, but when I build finite element models, I find that I don’t always get the model right the first time. :lol: Correction… I never get it right the first time. For tubular frame structures using (trusses and/or beams) I find I ev...

I've just run through all the beam section properties on the "Element Geometry" tab. And I'm finding some discrepancies. Although, I'm using my old college books, here are two pages showing the equations I'm using. http://en.wikipedia.org/wiki/List_of_area_moments_of_inertia http://en.wiki...

Hello Inquisitor, ... But - why using the Z88R solver from Z88Aurora? For a structure with less than 1,000 DOF with beams and trusses, the open source solver Z88R with the Cholesky option will do best. Best regards Prof. Rieg Hello Professor Rieg, Thank you for your quick response. It has been a lo...

I have my program creating these files: • z88control.txt • z88structure.txt • z88setsactive.txt • z88sets.txt If I start up Z88Aurora and open the project directory, I can see the generated model and successfully run a linear-mechanical and non-linear mechanical analysis, so I think I have generated...

I been writing a C#.NET application to help me generate the Z88 model input files. And I've noted that the analysis programs seem to be separate binaries in the C:\Z88AuroraV2\win\bin directory. Are these callable so that I can run the analyses on the input files my app creates? If so, is there some...

Don't know if you want any publicity :P... But I'm doing a little project for fun on a couple of other forums and wrote a post concerning your software. http://www.endless-sphere.com/forums/viewtopic.php?f=34&t=43496&start=15#p640193 and http://www.diyelectriccar.com/forums/showpost.php?s=26...

You have to pick elements in te picking menu, not nodes! Then you can deselect in the material selector "all elements" and you will see the element sets and chose them seperatly. I understood that in my original post. However, the element picker is disabled ! This video shows a simple two...

When I read the documentation about doing non-linear analyses and saw the list of elements (by their numbers) I didn't look to see what types those numbers represented and it wasn't even a passing thought of mine that beams would have been excluded. It wasn't till several days after I wrote the post...

Hlelo Inquisitor, it´s not a bug, it´s a feature. :D Greetings, Aurora_ico I love it! :lol: We use that one here at my day job all the time! Sorry, I thought I had digested the manuals. I must have killed the brain cell while watching the football game. I can live with, but... All finite elements a...

I’m working with 3D Beams (2) and I see the stresses in the z88o3.txt file, but when I am in the Post Processor and select “Stresses per element”, I get “No results available!”

Is this a bug or do I have something mis-configured?

Thanks.

Sorry. False alarm. I've figured it out.

I was looking for Tau xy due to the shear and its not available.

I just tested using a torque and found that Tauxx is the stress associated with torque.

As a former engineer that used FE on a daily basis, I have always felt it the responsibility of the engineer to evaluate the tools used. Even though, I’m no longer doing FE work professionally and this is merely a hobby, old habits die hard. I’m evaluating Z88 for its suitability toward my current h...
