Changes in Coordinates
Hai, I would like to apply Elastic foundation model for a grasp activity using wrist model. In order to mesh the segments of the wrist I imported the segments individually one by one as .stl files in a meshing software. I did this to have the same orientation of the wrist model so that I can have a ...

Re: Creating Contact surface on glass
arbitrary positioning of the contact spheres The spheres in the glass come exactly in contact with the spheres of the finger segments Image.tiff The parameters you use for the contact model may be another source of uncertainty Previously for working on grip activity of a ball, I had used Hunt cross...

Re: Creating Contact surface on glass
.depending on how precisely you need to model the shape of the object
This is how I created contact spheres sir. on the glass surface sir. Could you provide feedbacks on this

Re: Contact Modeling with OpenSim: a User’s Approach Public Forum
Hi I would like to perform a glass grasp activity using inverse dynamics simulation technique.Since both the finger segments and glass, both are rigid,I wanted to use elastic foundation model. 1.I made triangular mesh for all the finger segments in the wrist model since that is the requirement for p...

Re: Elastic Foundation model
As I have created contact meshes for the finger segments, I have wrote the below code <ContactGeometrySet> <objects> <ContactMesh name="f2"> <!--Body name to connect the contact geometry to--> <body_name>Iphalanx1</body_name> <!--Location of geometry center in the body frame--> <location>0.001 -0.03...

Viewing the contact mesh in GUI
Hi,
Could you direct me on how to view the contact mesh i created for the finger segments in my GUI window.Under bodies tab,it is not showing up to select.
Thank you

You haven't told us anything about how you are doing the analysis. Are you doing this in ID, Static Optimization, CMC? i am performing Inverse dynamics analysis.

Re: Elastic Foundation model
Hi , My objective is to obtain the joint moments of the fingers for the grasp activity of a glass tumbler. To implement elastic foundation,firstly I triangular meshed the finger segments and the glass . Created contact spheres on the glass in such a way that the contact spheres of the finger segment...

Re: Elastic Foundation model
The finger segments are in .vtp file format.What is the procedure to mesh it.I mean how to convert to a 3D read/write file format.Do you want to compute forces between the fingers and the glass? If so, it sounds like you do need contact at the fingers
