Not directly. If the loading is constant then perhaps creep strain energy is equal to the change in elastic strain energy (ETABLE,,SENE). Element volume is available with ETABLE,,VOLU so, in this example, creep strain energy density could be computed with commands like the ones below:
/post1
set,1,last
etable,sene,sene
etable,volu,volu
ssum
*get,sene_ls1,ssum,,ITEM,sene
*get,volume,ssum,,ITEM,volu
set,2,last
etable,refl
ssum
*get,sene_ls2,ssum,,ITEM,sene
creep_strain_energy=sene_ls1-sene_ls2
creep_strain_energy_density=creep_strain_energy/volume
/post1
set,1,last
etable,sene,sene
etable,volu,volu
ssum
*get,sene_ls1,ssum,,ITEM,sene
*get,volume,ssum,,ITEM,volu
set,2,last
etable,refl
ssum
*get,sene_ls2,ssum,,ITEM,sene
creep_strain_energy=sene_ls1-sene_ls2
creep_strain_energy_density=creep_strain_energy/volume
