==========================================================I have a copy of LISA FEA software. There is a free version that is limited to 1300 nodes. It has been a while since I have used it, but I recall using more than 1300 nodes.
It seems to be OK on simple models but, as already pointed out, creating a good model is the problem. With simple structures, like cantilever beam, the results are what you would expect from theory.
With LISA you can create a structure out of "elements", and an element can be defined as a tube. This would make it easier to model a fuselage, instead of defining a gazillion node mesh.
Thanks, I'll check out this Lisa FEA Software. Basically, most of these Tube and Fabric Ultralight Airframes I'm talking about, use only about 4-5 different OD Size Tubes in either 6061/4130 Tubes in .058" to .065". They use only about 2-3 Size's of OD Bolts and Nuts. Tube Connectors are basically the same used on all Tube Airframes. The Grade of the Bolts and Nuts used are High Standard. Some of us do have Plans of different Airframes to get the Spec's from the Manufacture/Designer. It would be just nice to be able to compare say a Cabin Hoop in 6061 vs 4130 and at different Sizes and Wall Thickness. Also to compare Weight's of the different Parts.
Clound Based just means you can Share your Design with others in the Company or with others around the World if you give them Access. Windows 10 has it built in so you can access your Files at Home or at Work, or in a Motel room, your Car, etc., as long as you got a Internet Connection.
Only Files you Backup to your Cloud is Accessable, People still need your Password to get Access. I have about 9 Desktop Computers and 3 Laptops used in my house, Networked in my House and even one Desktop in the Garage. Eventually I hope to CNC my Lathe and Mill or just switch over to CNC Mill/Lathe Tools and will probably have a dedicated PC using Mach3 or Mach4 with them also.
Is this your Web Site? http://www.homemadetools.net/builder/Aerowerx I just signed on, haven't really looked at it yet. But looks like a good idea for Home made Tools. Another good Reason to be able to upload a CAD file here.
