# 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?

There is function "Measures" in HV. Maybe that helps ? See my screenshot.

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"

Thank you very much! It worked very well

Thank you again
