  i want to calculate the starin modal energy using ansys workbench.
  is the potential energy and the kinitic energy the strain modal energy ?.
  I carried out the modal analysis, afterwards I carried out the harmonic analysis (solution) and under the harmonic analysis tab I calculated the potential energy + kinetic energy and the result is zero (potential energy + kinetic energy) = 0 on the whole body, why? where did I make the mistake ?.
