PLOT VELOCITY

Nancy Jewel Mcdonie

Hi all,

Can I plot the velocity - mag for my crash test? As I see, it is only velocity in 3 direction. 

Thanks.

Hi Nancy,

For crash applications usually we check the velocity of a specific node to have a precise idea of the effects.  These variables you highlight here are for the whole model.  So I do not know if it makes a lot of sense to see the magnitude of the total velocity of the model.

If you want to see this magnitude either way, you can use HyperGraph to combine the 3 functions you highlighted in order to create one that describes the velocity magnitude.

Hi, 

Thanks for your information. 

Can you show me the way to do?? I'm not really good at HG

Hi Nancy,

In the attached videos (Part1 and Part2) you can find how to create the curve of the magnitude of velocity components.

Take care because in x-axis you have to select only the values of one of the components as shown and for y axis you have to combine the values as the square root of squares (vector addition).
