Newbie question using couple sigma/w and seep/w

SamHarris

Hi, this is hopefully an easy one to answer - I am running a seep/w analysis which has quite a few time steps, each with a varying pore water pressure profile. I was hoping to use sigma/w to assess the effective stress at each time step (using a load/deformation analysis for each pwp profile from seep/w at each time step), but all i seem to be able to do is only select one pwp from the seep/w analysis at a time to analyse.. Is there something I'm missing, or can you not use Sigma/w to assess each pore water pressure profile from each time step in seep/w automatically?

Thanks in advance,

Sam
