nd stress of a plate that is supported at two opposite sides (rotational degrees of freedom are allowed) and gravity load is applied. By now I can only verify the displacement of the plate with a deviation of less than 3 % using ANSYS Workbench. Kirchhoff's plate theory as an analytical approach gives a similar result with 10 % deviation.
The van Mises stress and Principal stress results in Karamba are approximately 200 times higher than the results in ANSYS and the analytical results. I tried to find the mistake for several days now and would appreciate any help or similar problems with validating the shell stresses.
Here are the values of the plate:
length: 1 m, width: 0.2 m, thickness: 0.01 m
Material: Steel 'S235' (standard)
resulting gravity load: 0.157 kN
displacement in Karamba: 0.000583 m
stress in Karamba: 116 kN/cm² (=1160 MPa = 500 % utilization!)
stress in ANSYS: 0.57 kN/cm² (=5.7 MPa)
The utilization of 500 % for a steel plate under its own dead weight makes we wonder what is wrong... See the grasshopper definition and the picture attached.
Best regards and thanks for any help,

If you have multiple non nulls for a given index then the topmost one wins. If your lists are not equally long, then the short lists get elongated (i.e. longest list logic). This is why your first input gets repeated.
You'll have to find a way to make your first list contain 19 nulls, or, you can Combine list 2 and 3, then insert the one curve from list 1 into index 0 of the result.…

to create visual form, enabling parametric and generative design.
By the end of the session, you will understand how computer science can be used in design, be familiar with the Grasshopper interface, and you will leave with links to valuable resources that enable you to start your journey with this software. Also, there will be an opportunity to ask questions at the end.

tected that I get the same error always.
If you download this example and redimension the slider to 20, if you set it to 10, 12 or 19, you lose first row of points in surface.

Best.
p.s. I hope to debug this ussing VB.NET soon :)…
you post a screenshot of what the message coming from its readMe! output looks like?2) Close your Grasshopper and Rhino.3) Download "Revo Uninstaller Pro" from here. It is free for first 30 days, which is what we need.4) Right click on the RevoUninProSetup.exe and check if the file is blocked. If it is, unblock it.5) Run the RevoUninProSetup.exe file and install "Revo Uninstaller Pro".6) Uninstall "MapWinGIS" with "Revo Uninstaller Pro". It is important that "Revo Uninstaller Pro" deletes not only files from MapWinGIS installation folder, but also all other leftovers (as registry inputs). Here is a small tutorial on how to do that. Watch it from 6:10 till the end.7) Restart your PC8) When your Windows boots up, make sure that you are logged in as Administrator!9) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".10) Turn off your Windows Firewall.11) Then turn off your custom Firewall (in case you have another one, besides standard Windows Firewall).12) Completely turn off your Antivirus.13) Download again the MapWinGIS-only-v4.9.4.2-x64.exe.exe file from here.14) Right click on the MapWinGIS-only-v4.9.4.2-x64.exe file and see if it is blocked. If it is, unblock it.15) Right click on MapWinGIS-only-v4.9.4.2-x64.exe file and choose: "Run as"... Administrator.16) One the installation preparation steps start, choose "Full installation". Wait for the MapWinGIS installation to finish.17) Right-click on "Rhino 5" icon and then choose: "Run as administrator".18) Open the the ironpython_admin.gh file again, and again post a screenshot of the message coming from its readMe! output.19) Drop the "Gismo Gismo" component to Grasshopper canvas. Post a screenshot of the message coming out from its readMe! output.
So we will need in total three screenshots of the readMe! output messages.
Thank you once again for being patient, and sorry for the large number of steps.…

ger at the scale of rooms, walls and atria, but that of cells, grains and vapour droplets. Rather than the flow of people, services, or construction schedules, the focus becomes the flow of light, vapour, molecular vibrations and growth schedules: design from the inside out.
The sg2012 challenge, Material Intensities, is intended to dissolve our notion of the built environment as inert constructions enclosing physically sealed spaces. Spaces and boundaries are abundant with vibration, fluctuating intensities, shifting gradients and flows. The materials that define them are in a continual state of becoming: a dance of energy and information.Material potential is defined by multiple properties: acoustical, chemical, electrical, environmental, magnetic, manufacturing, mechanical, optical, radiological, sensorial, and thermal. The challenge for sg2012 Material Intensities is to consider material economy when creating environments, micro-climates and contexts congenial for social interaction, activities and organisation. This challenge calls for design innovation and dialogue between disciplines and responsibilities.sg2010 Working Prototypes strove to emancipate digital design from the hard drive by moving from the virtual to the actual in wrestling with the tangible world of physical fabrication. sg2011 Building the Invisible focused on informing digital design with real world data. sg2012 Material Intensities strives to energise our digital prototypes and infuse them with material behaviour. They have the potential to become rich simulations informed by the material dynamics, chemical composition, energy flows, force fields and environmental conditions that feed back into the design process.

sg2012 take place at Rensselaer Polytechnic Institute, Troy, in upstate New York from 19-24 March 2012. The Workshop and Conference will be a gathering of the global community of innovators and pioneers in the fields of architecture, design and engineering.
The event will be in two parts, a four day Workshop 19-22 March, and a public conference beginning with Talkshop 23 March, followed by a Symposium 24 March. The event follows the format of the highly successful preceding events sg2010 Barcelona and sg2011 Copenhagen.…
