Difficulty outputting/interpreting .sty variables in Radioss

Aslan_20571

Hi all, 

 

For a project, I would like to extract outputs (such as plastic strain, internal (specific) energy etc.) for each time increment of my radioss solution to python. The outputs in h3d or anim are not direcly interpretable, hence my decision to use .sty (ASCII).

The issues: 
- The specific/internal energies per element in the sty-file are not equal to those in the anim files (using hyperview), while the sampling time is equal. However, the distribution is the same, as each value is ~1/366200th of the anim results. Where does this random factor come from? Are the definitions of the specific energies different anim/sty?

-Additionally, the plastic strain results are all zero in the sty files, while the anim solutions in hyperview clearly show plasticity. 

 

What is going wrong here? Is there a better way to export these results without loading each increment in hyperview (for automation, I want to keep result extraction as simple as possible). 

Hope someone can help me!

best, 
Aslan

 

Edit: 

I am using the /OUTP command in the 0001.rad file. 
such as: 

/OUTP/DT (with the corresponding values 0 and 1e-3)
/OUTP/ELEM/EPSP

/OUTP/ELEM/ENER

The difference is coming from Anim values being Energy / Rho of your material

So, in your case, I assume your density is 1/366200 = 2.73e-6 (Aluminium in Kg/mm^3)

Another route you could use would be to use compose to extract the data from h3d directly

STY is solid internal energy, Anim is Element specific energy (internal energy/density)
