Re: Hyperelastic material with contact – looking for the best approach

Ok

 

Finally one simulation finished - the one with displacement input.

 

Some information that may help

 

It is a 1/2 model with mirror symmetry (similar to my 1st picture in this thread)

I let some of the CPUs free for other things in case the computer was scheduled to do something else overnight (does it make much difference?)

It was an overnight simulation (no other parallel use)

I set the msengine.exe process as "high" in windows

Processor    Intel(R) Xeon(R) CPU E5-1650 v2 @ 3.50GHz, 3501 Mhz, 6 Core(s), 12 Logical Processor(s)

Creo 2.0 M150

 

-----------------------------------------------

Run Settings

Memory allocation for block solver: 3072.0   

Parallel Processing Status

Parallel task limit for current run:           12

Parallel task limit for current platform:      64

Number of processors detected automatically:   12

 

Engine Command with the specified command line options:

mech\x86e_win64\bin\msengine.exe  b_Contact_Disp_input  -i  .  -w  .  -solram  3072  -sturm  default  -results_always  -num_threads  ALL_BUT_2

 

Model Type: Three Dimensional

 

   Points:              3031

   Edges:              17884

   Faces:               28246

   Solids:               13393

   Elements:          13393

   Contacts:           1

 

Memory and Disk Usage:

Machine Type: Windows 7 64 Service Pack 1

RAM Allocation for Solver (megabytes): 3072.0

Total Elapsed Time (seconds): 49266.76 

Total CPU Time     (seconds): 60761.50 

Maximum Memory Usage (kilobytes): 7821857  

Working Directory Disk Usage (kilobytes): 401552   

 

Results Directory Size (kilobytes):

326305 .\b_Contact_Disp_input

 

----------------------------------------------

 

My 1st impression is that the there is no significant bottleneck (although CPU time / Elapsed time could be better - have to check that).

 

So I´m afraid that there is not much to do to speed-up this type of simulation. Contact is a slow simulation - and this one took almost 17h.

 

Thus I think I have all the answers now. As final verification an overnight simulation is acceptable. If the goal is optimization it is needed something a lot faster - and as it was explained unfortunately 2D axisymmetric is the wrong simulation for this model.
