How to stop a job and continue calculation with HyperWorks Solver Run Manager?

Altair Forum User

Hi all,

 

How to stop a job and continue calculation from the end point with HyperWorks Solver Run Manager (Suppose a job is stopped and continue calculation with more cpus)? In addition, what's the effect of selections in the HyperWorks Solver View window? 

 

 

Any resources or videos will be appreciated.

 

Best Wishes

Hi Roy,

You can restart a run in RADIOSS. You can continue the run without modifying any definitions in Starter, run the (i+1)th Engine file (Runname_000(i+1).rad).

For Example:

•Run Starter: TEST_0000.rad

•Run the first Engine: TEST_0001.rad

•Run the second Engine: TEST_0002.rad > to continue the run after TEST_0001.rad

The parameters in the RADIOSS solver window:

 

INFO returns information on current cycle, current global energies, current time step.

STOP writes a restart file, R-file and stops the job.

KILL stops the job without writing an R-file

ANIM writes an Animation file

RFILE writes a Restart, R-file

CHKPT writes a .ctl file which can be used to restart the computation.

Hi George P,

 

Thank you for your reply. I don't think I have understood it. For example:

Two files were exported out by hypermesh (Starter file Tensile_0000.rad and Engine file Tensile_0001.rad). 

First, I run the job by selecting 'Tensile_0000.rad' as input file with HyperWorks Solver Run Manager (Figure below)

Second, I stop the job by using STOP options in RADIOSS Solver View Window.

So how I continue the calculation at the end point  with ncpu=5 by using HyperWorks Solver Run Manager? Which input file should I use?

 

Thank you

Roy

Hi Roy,

Create a second engine file with a name tensile_0002.rad. And run the second engine file after tensile_0001.rad. RADIOSS could restart the calculation from the last restart file which was created by running TEST_0001.rad.

In order to specify number of CPU cores, click on the options and click on nt option available and input the number of cpus.

Also, please go through http://www.altairuniversity.com/wp-content/uploads/2013/12/1036.pdf which explains on  HyperWorks Solver Run Manager.

Hi George P,

How to define the 'Tensile_0002.rad' file which is not exist in my folder? And which input file (Tensile_0000.rad or Tensile_0001.rad or Tensile_0002.rad or else file) should I use to continue the calculation?

 

Thank you

Hi Roy,

You can create a second engine file manually, ie in textpad. You can copy, paste the first engine file and can make the necessary edits and rename as filename_0002.rad.

Else, you can create the engine cards in HyperMesh and while exporting, select export engine file only option and rename the file as filename_0002.rad.

After the first run is complete, you can input the second engine file and can run to continue the run.

Hi George P,

I think the situation you said is about extending the run time. In other words, the run time defined in Tensile_0001.rad file reaches with normal termination. Then Tensile_0002.rad file runs to extend the run time.

 

However, the situation I mentioned is about stopping the job before the defined run time in Tensile_0001.rad. That is, the run time defined in Tensile_0001.rad file does not reach with User Break. My question is about how to continue the calculation from the breaking time. 

 

In addition, the Tensile_0000.rad file should be used as input file in  HyperWorks Solver Run Manager to calculate. so how to understand your saying ' After the first run is complete, you can input the second engine file and can run to continue the run '? Where should I select the Tensile_0002.rad file with HyperWorks Solver Run Manager?

'Hi Roy,

Please go through Restart in Help Menu. Everything related to restarting a job in RADIOSS is explained here.

You can directly input the second engine file in RADIOSS solver.
