Title: Getting solution summary for a coupled problem solved using "PARTITION"
Post by: anshulfy on August 05, 2021, 09:58:31 PM

Dear all,
I am using a user element and solving a coupled problem using PARTITION. After the run, I get a "Solution summary" for partition 2 only as it is solved later. How do I get the "Solution summary" for partition 1 also?

Thanks,

Do you mean the summary in the L* file (log file)?  I believe for partitions it is the sum of all things in the step.  If you want to get results for individual partitions you need to process the O* file for results.

Dear Prof. Taylor,
Yes, I mean the summary in the L* file. I think I am getting it only for Partition 2, but I will check it again.

Thanks,

Dear Prof. Taylor,
I rechecked the norms by comparing in O* and L*files. It seems that the L* file gives norms only for partition 2. Both files are attached. Please guide me.
Following are the input commands.

Code: [Select]

BATCh
  dt,,1e-2
  LOOP,,1e9
    TIME,,1
    PART,,1
      LOOP,,10
        TANG,,1
      NEXT
    PART,,2
      LOOP,,10
        TANG,,1
      NEXT
    STREss all
    PVIEW TIME
  NEXT
END

I think you will get the summary of norm values depending on which partition is active when you give the solution command TIME.
However, the total number of iterations between giving TIME should be the sum of all partitions.

There currently is no plan to change this.

Ok. Thanks Prof. Taylor.

maybe you want to trick FEAP by performing a time step with zero time increment:

Code: [Select]

BATCh
  dt,,1e-2
  LOOP,,1e9
    TIME,,1
    PART,,1
      LOOP,,10
        TANG,,1
      NEXT
   
    DT,,0
    TIME
    DT,,1e-2
   
    PART,,2
      LOOP,,10
        TANG,,1
      NEXT
    STREss all
    PVIEW TIME
  NEXT
END

It works. Thanks for your suggestion.
