Fail to generate transient profile data ?
 

I'm trying to export transient profile data and using it as an input in next boundary condition. Until this stage, I can export steady state data where its spatial field equals to [x,y,z]. However, it does not apply if I want to produce transient profile data with spatial fields [x,y,z,t]? I cannot find any option time in variables (File>Export) . Can anyone shed some lights ?
