Hi Forum,

I am trying to create a pressure vs distance plot and want to be able to extract the pressure along a line at a given time. Is there a way to do this? I know VisIt (LLNL post-processing tool) can do a 'Lineout' that allows the user to draw a line and will do this. Is there an equivalent in LS-DYNA?

Thanks,

Peter

Also, is anyone aware of how to capture history information in a S-ALE simulation? Everytime I try to capture a element variable with respect to time it just crashes...

Thanks,

Peter

Hi All,

I was able to solve this. For those that are interested, feel free to keep reading the solution. For the distance along a line, it is really easy. When you click "post" in the right hand tree, you will see another button in the tree that is "history". History usually indicates the variable of interest vs time. However, there is a checkbox to do 'along a line' that you should see in the window. 

If you are doing SALE, like I was... this selection wasn't working. The key here is that you have to make sure that you have the solid elements checked. It won't work if you are choosing the ALE elements. At least for the pressure quantity. That seems to be stored in the solid element and not fluid element. I can provide photo guidance if not clear.
