How to Plot Total Deformation vs Time Graph for the Dynamic Crash Analysis

Hello everyone,

I am performing the dynamic front crash analysis of the chassis of a vehicle in Radioss. I want to plot the total deformation vs time graph in the Hypergraph for the results obtained but I am not sure how to plot it. I have also checked all the global variables used to plot graphs but I didn't find the global variable for plotting deformation vs. time graph. (Also attached an image for reference).

Does anyone know how can I plot the above-mentioned graph? Any help would be appreciated.

Thanks in Advance

    By 'deformation' you mean actually, element Strains?

    Or do you mean Displacement?

     

    Any of the above is stored into the H3D or 00XX animation files, by default. So in order to plot them over time, you need to load these files instead.

    Although I believe you can also request these results to be stored into the T01 file, but you would need to add an OUTPUT block for the specific nodes/elements you want to push the response for.

    Does it make sense to you?

    Hello @Adriano A. Koga 

    Thanks for your reply. By deformation I mean displacement. Also, would it be possible for you to guide me on how to create an OUTPUT block request to obtain the displacement vs time plot for the particular elements or nodes? Attaching the hm file of my model in case you need it.

    Thank You

    if you have the H3D result file you would be able to plot displacements in HyperGraph. Have you tried?

    The only downside is the result frequency, which is usually smaller.
