I have downloaded the bouncing_sphere.oism model but it gives error once I want to open it in opensim. The error indicates that either the model does not exist or I do not have the permission to access the model. Can it be due to different versions of opensim that I am using?
Thank you with your help in advance

Hello,
The same problem is now happening to me, I also tried earlier version 3.1 but the error is the same... did you make it already? Thank you

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 performing elastic foundation methodology.
The below piece of code is where i used Contact mesh methodology for the finger segments.
Code: Select all
<ContactMesh name="f3">
<!--Body name to connect the contact geometry to-->
<body_name>Iphalanx2</body_name>
<!--Location of geometry center in the body frame-->
<location>0.00075 -0.015 0.0005</location>
<!--Orientation of geometry in the body frame-->
<orientation>0 0 0</orientation>
<!--Display Pref. 0:Hide 1:Wire 3:Flat 4:Shaded-->
<display_preference>4</display_preference>
<!--Display Color-->
<color>0 1 1</color>
<!--Filename that contain mesh geomtry (supports .obj, .stl, .vtp). Mesh should be closed and water-tight.-->
<filename>fingers3.stl</filename>
</ContactMesh>
<ContactMesh name="f4">
<!--Body name to connect the contact geometry to-->
<body_name>Iphalanx3</body_name>
<!--Location of geometry center in the body frame-->
<location>0.00193 -0.03277 0.00472</location>
<!--Orientation of geometry in the body frame-->
<orientation>0 0 0</orientation>
<!--Display Pref. 0:Hide 1:Wire 3:Flat 4:Shaded-->
<display_preference>4</display_preference>
<!--Display Color-->
<color>0 1 1</color>
<!--Filename that contain mesh geomtry (supports .obj, .stl, .vtp). Mesh should be closed and water-tight.-->
<filename>fingers3.stl</filename>
</ContactMesh>
2.For the glass part,I meshed it.My question is whether to create contact spheres on the glass and fingers so that force will be produced if the fingers come in contact.
Kindly help me out here.
