Rename files - Windows

Hi guys.Have any of you played with changing file names of large number of existing files? E.g. a lot of PDF files with a slight change in all filenames?I guess it could/should be done through Python…Continue

GH Python - Live output/update

Hi guys.Is it possible to get "live updates" from the Python script? It is for when I have scripts that take a while, running a lot of loops, it would be great to be able add print commands that…Continue

Hi.I am using layouts to print "screenshots" set up in Grasshopper to PDF, however I very often get this miniture scaled window of some of the geometry when I print the PDF.It doesn't appear in the…Continue

Print layout from GH

Hi.Has anybody worked with automatically printing the Rhino Layout to e.g. PDF from GH? I guess a script that controls the Rhino Document and then use command Print, might do some of the trick, but I…Continue

"Dear Balazs, the cross section optimizer in Karamba does not update external loads. It only updates the dead weight in between optimization steps. In your case one would have to introduce an additional loop (e.g. using Hoopsnake) where the cross…"

Hi

You should go to   http://www.shiplab.hials.org/app/shipmotion/

then right click and  select  view page source  command  ,you found the hydrodynamic  code that is used  in the site , and which is well documented   in the document attached

i managed to  "wire"  that code in grasshopper (look at the png)  ,it is only a matter of rhinocommon ,the motion RAO's (Heave, Pitch and Roll ) combined with Sea spectrum gives the time domain ship motion ...

I will  soon documet this application ,and may be share it ,but now unfortunatly

I'am very busy with the Probabilistic damage stability modeling , a question of one month max ...

Best regards Msahli

workflow of karamba together with kangaroo can be that 
1) you modify a mesh or lines with kangaroo, e.g. generate and modify a hanging model
2) take the mesh or the lines as structural elements in karamba, and every time kangaroo updates the geometry (interval can be set), karamba calculates the structural response
3) size the cross sections of the structure according to the member forces
4) use galapagos determining certain parameters of the model, e.g. unary forces in kangaroo to adjust the model
.... ;)

Hey rasmus, you are right, both with karamba and my thesis. And for the gridshell- we did not know about that one but had a similar case. Karamba comes with a component for iterative approximation of large deformations.. And most of it is free.

Hej Rasmus. Vil du være interesseret i at komme ud på Danmarks Designskole og fortælle lidt om, hvad du aktuelt roder med i Grashopper? Det kunne fx. være fredag i uge 43. Think-it-over og svar her på forum.
