Can any body give me source links to the basic formulation of the angle term of Modified Morse Potential, which gives the bond energy due to bond angle bending.

Angle term of the Modified Morse Potential is provided through the below paper.

I have been working in Numerical Simulation for sometime and would like to work with people who are familar with numerical simulation and are working for a certain paper right now or planning to work. I am located in Ethiopia. I am not  familiar with the research community, and instructor in one of the  university  in the country. If you are interested, I am eager to work. As it is one way of helping me  to introduce my self to the research community, while working on a certain paper, and further opens a way for addition works. 

Thanks 

My own DEM(Discrete Element Method) program's solution for static problem seems strange.

I use my program to calculate the displacement of a cantilever under static pressure:

1. it seems my program shows convergence for static problem as the mesh gets denser. As the mesh grows denser(that means the particle becomes smaller), the displacement(of y direction)  of the free tip becomes smaller.

Hello,



I have to design the body of a truck. I need some documents such as standards, practical recommendations, papers that could help me for the calculation of different type of loads applied to the structure of the body. This could be wind, gravity, acceleration, etc. Could you please help me by giving some information.

Thanks in advance,

Goli

Hello,

I try to enter a triangular load on an area. I have entrered the gradient information in settings. But when I try to apply load on area, it does not take it in triangular form, but in constant form. It works  with apply on nodes. But, is the result correct with this option?
