Compute fluid forces and/or total energy

201270853

Hi

Is it possible to compute the combined force of all fluid particles or the total energy in the simulation? I would like to compute damping and natural frequencies of a TLD and thinking that using the sum of particles would be more stable and somewhat independent from dp.

Is the post processing tools able to output that or would it be necessary to modify the code?

Dear user,
The code needs to be modified to compute the total energy.
If total energy=potential+kinetic+thermal, the post-processing tools will allow you to compute potential (z values) and kinetic (velocity values) but not the thermal.

The potential and kinetic energy will be sufficient. Computing the velocity is "-vars:+vel", but how do I compute the z-values?

Alex

perhaps you can create output data in ascii format and there you can read the columns of z position and velocity values
