Derivative of Metric Tensor
Hi All,
How can we compute the derivative of metric tensor on one manifold with respect to metric tensor on another menifold?

Nonlinear static in SAP 2000 (Problem with hinges assignment)
Forums
Hi everyone,
Currently I am working with nonlinear static pushdown analysis in SAP 2000. I understand that when the analysis gives a warning 'unable to find a solution at step 20' means that the assigned hinges are compete to unload i.e where one hinges requires the applied load to increase while the other requires the load to decrease.
My question is, how are we going to overcome this warning?..Is there any better solution for this?
Looking forward for anyone to reply.
Best Regards,

how to mesh two sucessive volumes with different meshing
i've modeled a column as a volume
i need a closer or finer mesh near the junction of beam
anyone pls guide me on this issue???

Can anyone recommend books or papers that use RBF in meshless method? I will like to know more about how to use RBF in meshless methods to solve PDE. Matlab code on this subject will also be appreciated.

ANSYS Meshing Problem
Hi I am currently using ANSYS 13 Workbench to do FEA on .igs files of leg bones (femur, tibia, and patella), I am new to ANSYS and I am having trouble meshing the bones. I am able to mesh the bones individually however when I import the whole leg assembly (assembled in proENGINEER) it will not mesh. Does anyone know how I can fix this?
Post-doctoral Position in the Ohio State University
Post-doctoral position is available in the area of ultrasonic material characterization and nondestructive evaluation (strong background and experience in ultrasonic experiment and modeling are required). The position is supported from research grants. The focus area is ultrasonic study of nonhomogenous materials like polycrystalline materials, composites and adhesive bonds. State of the art ultrasonic laboratories and other characterization facilities are available. More details will be provided to interested individuals.

ASME IMECE 2012, “Mechanics of Adhesion” symposium
Adhesion has long been an important issue for mechanics and
many other disciplines. Its influence spans macro-, micro-, nano- and molecular
scales. When size goes down, adhesion plays a more and more significant role.
Many important technologies attribute to adhesion, such as transfer printing
for advanced microfabrication, super adhesives inspired by gecko foot hairs,
and self-assembly. Adhesion also has strong implications on the behavior of
nanomaterials (such as nanotubes and graphenes) and biological systems (such as
cells). This minisymposium "Mechanics of Adhesion" is to provide a
Cam Follower Mechanism and energy efficiency
You can see practical model of cam follower mechanism for clean energy.
Follower move little bit and help cam to rotate 6 times more peripheral
length. Cam can rotate 360 degree using two followers. You can get full
