No Animation files being created
Hello!
I am currenlt using Hypermesh to simulate a crash box. My model has Zero intersections and penetrations and the model check also Shows Zero Errors.
During Simulation, the error keeps on fluctuating negatively between 0 and -2% and the dm/m value is also very low but constant=3.4636e-02
In the Simulation file, only one Animation file is being created i.e. A001. How can I Change the model to obtain the further Animation files?
Thank You!

Hi,
you have shared the starter file which does not contain simulation controls.
Use Tools>engine file assistant to set up the simulation controls. Define animation output frequency ANIM/DT to get the animation output.

Hi,
Thank You for your Reply.
I have already defined ANIM/DT with TSTART=0 and TFREQ=1.
Still not able to get Animation files.

You're welcome.
No animation is output because the simulation ends at 3e-3 which is far less than TFREQ=1. 20-50 animation frames are usually output so TFREQ should be /RUN/Tstop divided by 20-50.

Unfortunately, even having different iterations of TFREQ and TSTOP is not working. I am getting the same values for time step and only one Animation file.

Hi,
you are not getting the animation output because the simulation runs so slow it does not even reach the animation output interval defined. The reason simulation runs so slow is because of the low timestep which is 1.3e-7 ms, while the usual timestep is on the order or 1e-3 ms. The timestep is related to the Size of the smallest element (characteristic length) and Sound propagation speed (stiffness and density). While you can not change the material properties, you can remesh with larger element size and apply timestep control. For more details see the attached document from free Radioss ebook:

Thank You!
This one really helped to get results.
