Rafael Pastrana replied to Leonardo's discussion Infinite axial stiffness in the group karamba
"Hey, What about modifing your cross-sectional area by a very high factor with the "Modify Cross-Section" component? This should leave your E Moduli an Inertia intact...Best, Rafael"

Rafael Pastrana replied to Yunlong Tang's discussion reasons for Singular stiffness matrix issue in the group karamba
"Hi YunLong, Apparently, 2 of your lines are not connected to the others, and I think this is why Karamba shows an error. You could always use the "Connected Lines" component to see if all the lines are properly connected. In these case,…"

"Hi Yunlong, Is your grasshopper and rhino files the right ones? Tried to open them but it apparently looks like there are no properly referenced curves....See screenshot below. Best, Rafael"

"Hello Ahmed, Maybe you have to Click on the "Select" button to deploy the component menu?? Please see screenshot attached. Hope this helps :) Rafael"

"Hi Andrei, have you had a look to the "prescribed displacement" component? I guess this one will help you out with what you want. cheers, Rafael."

Rafael Pastrana replied to Patricia Edith Camporeale's discussion convert text to number in the group karamba
"Hi Patricia, If you want to get the maximum displacement or utilization of elements as a numeric value, you could rather extract it from the "NodeDeflection", or "BeamUtilization", then flatten the list (in case you have…"

"Hi Andrei,I guess you would need to move the point that defines the aforementioned support in order to do that. Best, Rafael"

Rafael Pastrana replied to Patricia Edith Camporeale's discussion relation between steel bar/concrete amounts in the group karamba
"Hi Aryan, I think that deflection-wise it could be okay to assume concrete properties for having a first glimpse into the deformation of your structural system in such a conceptual stage.  Theoretically speaking, I believe one of the ways of…"

Rafael Pastrana replied to Patricia Edith Camporeale's discussion relation between steel bar/concrete amounts in the group karamba
"Hi Patricia, I think there is no such a "direct way" to just get of getting the steel rebar percentage in a concrete structure straight ahead from Karamba.  As far as I know, Karamba is a finite element method piece of software which…"

"Hi Jon,  I'd like to be part of the testing. I second Markku - getting to export shell elements would be a great step. Best, Rafael"

Force-Flow Lines into Structure

Hi everyone,Any thoughts on a workflow to translate the force-flow lines of a given shell into structural lattice?I've tried but certainly the resulting flow lines are very dispersed and abundant so the only way I've figured it out to make it work is to do it manually. The intention is to achieve something like Pier Luigi Nervi ribbed structures or like the CIAB Pavillion from Zaha Hadid.…See More
