Histories

Home Screen Process Flowchart

• The results can be viewed by selecting the view button on the task bar. A seperate window of LS-OPT Viewer opens up.

LS-OPT Viewer

1. Select under Simulations the item Histories.

Plot Setup

Setup the plot for pct2

1. Select the Setup tab.
2. Select n for the iterations setup.
3. Plot co-ordinate selections :

x axis : time

y axis : s2

• The first plot in the image depicts a plot of the stress against time.

4. In the similar way plot the strain curve by changing the y axis entity to e2.

5. The loading cycle curve can be illustrated using the choice for the y axis as s2_vs_e2 and test2. We can notice the hysteresis for the cyclic loading case.

Multiple Plots

1. Select the Multi option to view all the simulation crossplots and test curves simultaneously.
2. Select n for the iterations setup and select the last iteration to display the optimal curves.
3. To view all the stress-strain crossplots viz. s2_vs_e2, s4_vs_e4, etc. select the respective boxes.
4. Similarly select all the test curves viz. test2, test4, etc.
5. To distinguish between the crossplots it's convinient to select the  Neutral option for the Color entities. 

Convergence

1. Select any of the history curves. In this case s2_vs_e2 plot has been selected.
2. From the file histories select the corresponding test curve, e.g. test2.
3. To observe the convergence over the iterations choice is made for all the iterations.
4. To distinguish between the iterations choice of Color entities is made on the Iterations.
5. Select the Options tab.
6. To show the optimal curves over the iterations the Only optimal option has been selected.
