Hello,

 

I am trying to check stresses in a model in lsdyna. The stresses can be shown at each time step using FriComp option and it shows the maximum and minimum values for this time step as well. Is there a way to determine at which time step we have the maximum or minimum stress. Or, to set a limit to show the time steps with a stress exceeding this value. Additionally, is there a way to show an arrow on the view to show max and min stresses locations similar to what we have in ANSYS. 

 

Thanks

Hello,

For this: "Or, to set a limit to show the time steps with a stress exceeding this value."

you can fringe a boolean valued expression as shown here:
