Assignment 3-2D Element Formulation Challenge

OBJECTIVES:

1)To change the run time to 55ms

2)Change the number of animation steps during simulation to min 25 and max 60

3)Run the basr simulation without any modification to element properties

4)At the end of the simulation,do the energy error and mas error checks and determine whether results would be acceptable.

5)If acceptable, Plot rigid wall forces ,internal energy ,hourglass energy,contact energy,total energy of the simulations.

6)Change all the shell elements properties to recommended properties,save this as separate,rad files and the simulation.

7)follow steps 5 and 6

8)created a brief report comparing all the results from steps5 and 6 for both simulations.

First imported the file.

for that go to import solver deck and select import solver deck option.

choosen file tye as RADIOSS, after that choosen file of 0000.rad andimport it.

1) for this I choose cards> engine_run card and changed the T_stop value as 55

2) for this I choose ENG_ANIM_DT card and put the value of Tstart& Tfrequency as 25 & 1 respectively.

3) for this gone to radioss command.(Analysis>radioss)

after that added the path where requiredto save files

here main points are(-nt 4)value options

ater running the simulation hyperwork solver view showed the results obtained from simulation and shown the processinng timeing.

4) checked the error of energy &mass.

the acceptable value of the energy is -15 to 5 percentage and for mass error is 2 to 3 percent.means here error value is in the range then it acceptable.

Now changed the hypermesh to hyoerview and load the .h3d file. It is used to view the results to run the animation file.

plotted the rigid wall forces vs time graph.

thats how the results are obtained.
