CPU only uses only 20% when running composite analysis for abaqus

[d.g.van.pelt]

Hello!

I am using composite analysis and abaqus to simulate failure on a 3-point bend test. I used tutorial 1 as a reference, but when I submit the job for abaqus in the command, it only uses around 20% of my CPU. 

A calculation is taking ages (no, really a working day) ! How can I solve this? Also my ODB file gets around 10GB! Is that normal?

I have an Intel i7 3,5ghz 32gb ram running windows 8. My model consists of 100.000 elements. Is it too much?

Thanks in advance

David

Hi David,

A few suggestions:

1. Open your abaqus_v6.env file and add the line 'cpus = 2' to use multiple cpus.

2. To reduce the size of the results file, you could request fewer outputs from the Field Output Requests Manager in Abaqus.

3. Double check to make sure you are using the nonlinear solution controls that work best with Simulation Composite Analysis.  See the links below for specific details on this.

100,000 elements should not be a problem.

Hopefully this helps.
