How to resume the current analysis?

      I want to resume the current analysis from ealier time step. The documention in "Help" indicates there are 3 kinds of different methods. But I find the true operation process is  quiet different form the documention. For example: 

 

1.Extending an  analysis:  ........4.Selecting the"Analysis : Perform Analysis..." command ,and specify how much longer you want to extended the analysis in the "Extend Total By"....

   In fact: If we select "perform analysis" command.  Algor will start the analysis immediately. How to set the extending time?

 

2. Resuming the Current Analysis: What I can find in Algor is "Restart  the current analysis", and the "restart from step"( not "resume from step") is always to be "0"(unchangeable). How to change that to the  ealier time step? Thanks.

For your first question, how to stop automatic analysis. In options->analysis, unchecked "automatic analysis".

 

"restart the current analysis" is the right one for you, I guess. You just choose that one, and it will resume the current unfinished analysis.

 

For example, the current analysis stops at step 45, and the total step is 100. "restart the current analysis" will continue from step 46. The previous 45 steps of results are still there.

continue the example

I  want to change the loading curve from step 20 to 100. 

How to let the analysis restart from step 20 ( just reserve previous 19 steps of results),not from step 46~100?

Thanks!               Ccz90

If you want to change the load curve, you have to "restart from another directory".

Finish the analysis to step 20 in DS1, and then copy it to DS2, and update the load curve, then let DS2 restart from DS1.

But in this example, the current analysis stops in step 45, not step 20. I don't want to run my program  from step 0 to 20 again(wasting to much time).What I want is to resume the current analysis  in earlier step . Your reply seems telling me the only way is run the program "again" from step 0~20, then step 21~100. 

  Now, my problem is  the setting of "Restart from step" is always to be 0(means the last converged time step). Is there any methods to change that become step 20? Thanks!

Hi Ccz90,

When wanting to re-start an analysis from a step other than the last time step, you need to indicate that you want to save the re-start steps BEFORE running the original analysis. See the paragraph "Saving Multiple Restart Times" on the page "Autodesk Algor Simulation > Setting Up and Performing the Analysis > Setting Up Part 2 > Nonlinear > Analysis Parameters > Advanced Settings > Performing a Restart Analysis".
