"You can also create a label for the section type and dimensions you want. There is an example of that in my tube truss bridge that you can use as a reference. Use the help function in GSA to find the abbreviation for a rectangular section."

"I'm not sure if this is true for GSA (or even the same feature), but in general FEM analysis software enables the option to find structural nodes which lie close to each other, but aren't actually connected to the same elements. Imagine…"

"If the GG plugin changes the input values from my model 'one-on-one' to SI units, this may very well be the source of my problems: i.e. converting my model's (mm) to GSA's SI units (m) "

"Hi Jon, I've tried all kinds of settings in GSA (including the default setting). Changing them doesn't seem to help: if (for example) I change the length units from meters to millimeters, GSA scales the input sent from Grasshopper by a…"

Michael van Telgen replied to Jon Mirtschin's discussion Oasys GSA in the group Geometry Gym BIM

"Hi Jon, I was wondering if there is an easy way to switch between units (for instance meters and millimeters), when analyzing a structure in GSA. My tensegrity dome analysis definition was based on mm and kN, but apparently GSA thinks this should be…"

"That's a very broad question, can you be more specific? I cannot help you with building your definition, I simply don't have the time. Regards, Michael"

"I made a change that the solver output is now grafted (if you were querying similar results data was getting mixed). So I've attached a revised version of Michael's file that flattens the output to get the same result."

Tube bridge optimization

Hi everyone,Today I've uploaded a second video regarding the possibilities of doing an optimization using SSI for GSA, Galapagos and Grasshopper. Be sure to watch it in HD! The GH definition can be found in the attachement below.This video deals with obtaining an optimization regarding the design of a tube bridge, inspired by the Harthill footbridge, the Greenside Place Link bridge and the Corporation street bridge. A solution is found using the Galapagos evolutionary solver in Grasshopper. An…See More

Truss optimization example

Hi Everyone,Last week I decided that it would be fun to analyze some structural engineering problems and solve them by using a combination of GH, SSI for GSA and Galapagos. :)In today's video I'll deal with the design of a simply supported planar truss.Next week I'll explore a bridge based on the M8 Harthill Pedestrian Bridge design.Please post any questions you may have in the comments and I'll gladly answer them. The definition is included below.MichaelSee More
