Hi,
I am getting the following error: “Supports with the following indexes: 73,3535,5065,8494
There are already supports defined identical degrees of freedom at the same position. In case you sum up the reactions of all supports this will lead to a wrong resultant reaction force” when i input my supports? How can i rectify the warning message? im using an imported 3D scanned mesh for analysis.
hello
use at the remove duppint before connecting the point to support.
Hi,
What do you mean by that? Thanks!
you have duplicate points which you are using to define the point, so simply eliminate the duplicates and you will no longer have this error
okay i got it! thanks! I have another issue. im trying to do a simple compression test on the above cylinder and I’m using load case 0 to apply point loads on a list of points (top of the cylinder) but the results i’m getting seem pretty extreme eventhough the supports at the bottom of the cylinder are fixed in all directions (translation & rotation).
Disclaimer: I’m aware that the method used to filter the required points for both the supports and loads are inaccurate especially since the surface is irregular but i’m trying to see if I can set the simulation up to begin with hahaha so any help will be great!
Hi, are your units correct? When I open the file it is a 14m diameter cylinder with 1cm thick concrete and you are applying 37000 kN in load in total
Hi,
the model is actually of a scanned 3D sample and the actual diameter is in the milimeters. Is there away to change the units i’m working with in Karamba3D? Also is the thickness of the concrete changed using the height parameter? Thanks!
yes, you can set everything either in the toolbar (version 3) and the cross section thickness is also set in the cross section
okay! The actual object is solid throughout though, is there a way to replicate this with the model in karamba for the cross section?
Karamba3D does not support the analysis of solids, only shells.
