Extract nodal kinetic and strain energy transient analysis

[Anonymous]

Dear all:

I'm modelling a non-linear transient response. The aim is to simulate an impact, and the analysis includes a force with a given duration (scale factor vs time).  Is it possible to extract/write kinetic and strain energy of my model for a given time step?

Many thanks,

Erik

Hi @Anonymous 

The kinetic energy is not an output.

See these items for the strain energy:

• Forum post from last month: Energy balance in a non-linear transient analysis
• Article on the Autodesk Knowledge Network, as a result of the above forum post: How to output strain energy in a Nastran analysis

Hello john.holtz

Many thanks for you reply.

I will have a look at the posts, and maybe kinetic energy will become an output one day?
