If your computer is still too slow we can organise a swap!.

Also , I have noted that your computer has two processors while mine has only one.

Does this affect ?

 

I used Automatic solver = SparseM,so it does not matter.

Do not you have any "power saver" option on?

Dear Rafal

 

Sorry , What do you mean by " power saver "?

 

Thanks

Something like the option in notebooks : in case of no activity slowing down hard disk or diming screen....

MUltithreaded ~1h

 

14:44:28 - Start of analysis #1
14:44:28 - It is suggested to use 'DSC algorithm' in case of dynamic and non-linear analysis of structure containing released directions.
The DSC algorithm option can be switched on in the 'Job preferences' dialog box (the 'Structure analysis' tab).

Dear Rafal

 

Good morning

 

First Trial

 

It has been done under the following conditions :

 -  turn off the display (10 min) .

-  Method of solving (Automatic) .

- Save results of quadratic combination (Active)

I got the results after  77h16min , and I got the percent of mass participation more than (90%) after 168 mode .

 

  Second Trial (pls ,sse shot 02) 

 

It has been done under the following conditions:

- Turn off the display (never)

- Method of solving (Multi- threaded )

- Save results of quadratic combination (Not active)

I got the results after 2h28min , and I got the percent of mass participation more than (90%) after 127 mode.

 

 

 

 

My Inquiries are :

 

 

1 . Do you agree with me that the processor affect  the calculation speed as it appears after comparing the time calculation  between us using multi-threaded solver?

 

 

 2. why  does the number of modes decreased in multi-threaded?

 

Thanks alot

IN case of multithreded solver- yes - you can compare yours and mine times.

IN auto \ SparseM sover the times should be comparable

 

 2. why  does the number of modes decreased in multi-threaded?

 

I will check

I think you are working on different models.

It is enough to run 50 modes on mine : http://www.4shared.com/zip/r9UILvSV/Strucutral_meshed1.html

Dear Rafal

 

Actually , I am working in the same model but the settings are different.

I have noted that when I activated (inactive) in (model analysis parameter ) then I need to use more number of modes than if I activated (percent of mass participation ) to get (90%)

 

Do you agree with me or there is any another opinion

 

I appreciate your good cooperation
