assignment-3

1) Above image capture is a first part of this assignment and in this part i just changed the total runtime of simulation and no of animation files that your mentioned in this assignment.

*From the output file that i absorbed-This method is not acceptable because Energy error is more(above the 5%) and mass error is constant for both the model and in this model total energy is not a constant and in this model have hourglass energy error.

2) This is the second part of this assignment and here i modified the properties that your mentioned in this assignment.

*From output file that i absorbed-This model is acceptable because Energy error in this model is low (below 5%) and mass error is constant then there is no hourglass error in this model so there is no energy dissipation before the simulation. In this model have sudden rigid wall force rice at the end this one indicate elements got more displacement and less stiffness.

*COMPARISION:

*Both the model have zero contact energy

*First model elements have more stiffness and second model elements have less stiffness and more displacement

*first model energy error is more and second one has less amount only.

*first model has hourglass error in second model there is no hourglass error.

* Total energy for first model is not a linear curve it got decrease this is due to hourglass error in second model Total energy slop is constant.
