Distance between nodes

Recommended Posts

Hello everybody :)


 


I'm working with ls dyna as solver and have a question about distance measurements.


 


I want to measure the distance between two nodes during a simulation. I simulate a moving sled with a person on it. The distance between two nodes of the person should be compared at the beginning and after a certain time is over.


 


Does some of you maybe have an idea how to measure and compare the distance of two nodes?

Thank you for your quick answer! :)


 


I will try it this way. 


 


How I've already written, I measure the distance between two point. To be more specific, I measure the distance between two nodes, which are located on a rib of a human model on the left and right side. This distance - before simulation starts (before impact to the whole human body begins) - should be compared to the distance of this two nodes after simulation. 


 


Is it possible, to write a (mathematical) script in hyperview, that calculates the quotient ( new distance / initial distance ) ? Or do you have another idea for this problem?


 


Thanks for supporting again!

It is possible to create scripts in HyperView, see Hyperview help for more information on this,


 


however I am surprised you need to automate this, when you can use " measure" as suggested above and just divide it easily with the initial value,


 


When you are in the measure panel, you can just say create curve and then divide with a particular value etc in HyperGraph y defining a new curve with "math"
