Improving the speed ofmy computer (hp Z800 workstation)

Dear Sir

 

Can you help me to improve the performance of my computer(the speed), where I am doing dynamic analysis for concrete tower using (200 mode) , the finite element size(1.00m) on the version (ARSApro2013), whereas the program takes more than (60 hours) until I can get the analysis results.

Knowing that my compture(hp Z800 workstation) specifications as attached.Although , I've developed  it from (6 GB RAM) to (48 GB RAM) and don’t note any improvement in performance (increased speed).And the graphics card specifications as following :

GV-R795WF3-3GD

AMD Radeon HD 7950/PCI-E 3.0

3072 MB GDDR5/384 bit

Could  you guide me how to increase the efficiency of the computer (increase speed) or what way I can get the results of the analysis faster than (60 hours)?

 

Thanks

1. Selweigtht as mass for modal analysis duplicated in your model (1: from modal analysis settings, 2: load to mass conversion) 

2. Results for such settings:

Dear Rafal

 

In the attached model , I have noted that some simple cases aren't included in the (Automatic Combination"ACI318-2002 ) such as case number (1 , 2 ,3....etc) and some of them are repeated , also there are some combination cases such as (1.20DL+1.60 LL) aren't included in combination case .

Please   see the attached capture .

 

http://www.2shared.com/file/X9or4OSn/Strucutral_meshed1-Disrgard_de.html

 

Kindly , Could you help me to get all combination cases according to ACI318-02?

 

Thanks a lot

Thanks for reporting.

Just component definition (name=display is wrong - internally everything is OK).

COnvert code combinations onto manual ones to see that everything is OK for calculations.

Example:

Dear Rafal

 

In the attached file, I have calculated the required reinforcement for RC-Wall using (ACI318-08M), for first run without using the Amin , I found out that in the vertical reinforcement, the required steel area is less than the minimum ,after that I used in the second run Amin for finite elements, their steel area is less than minimum and greater than zero but I have noted that ROBOT used twice the steel area minimum for some finite elements .

Pls , could you verify this point ?

Note : Kindly , if there is any capture . please send it as attached
