I would like to plot the impact pressure versus time plot for a bird strike analysis. I managed to plot the impact force vs time using database RCFORCE card. The model I have is a bird impact on a rigid plate where the bird to plate contact is defined using AUTOMATIC NODES TO SURFACE CONTACT (Model k file). May I know how to extract the following plots in LSDYNA?

1. Impact pressure vs time for the bird part

2. Impact pressure vs velocity for the bird part

Thank you

I figured it out. In the post processing tools. Select history, under that set E-type to Sphnode. Then we can select the SPH particle for which the pressure vs time plot required.
