| If the active dataset happens to be a transient dataset, two options are available:
| | #REDIRECT [[Template:Steady State vs. Transient Interpolation]] |
| | |
| #Steady state interpolation can be performed using only the selected time step of the active dataset. | |
| #Transient interpolation can be performed using all of the time steps.
| |
| | |
| By default, only the selected time step is used. The time step is shown next to the data set name at the top of the dialog. All of the time steps can be selected by selecting the Use all time steps toggle next to the Time step combo box. If all time steps are chosen, GMS begins with the first time step in the list and repeatedly interpolates from the scatter point set to the target object, one time step at a time, for all of the time steps. As a result, a dataset is created on the target object with a set of time steps matching the time steps on the scatter point set.

| When performing transient interpolation with the [[GMS:Kriging|kriging]] option, special care should be taken with regard to the variogram. Since each time step represents a separate set of data, technically, a separate variogram (or set of variograms) should be created for each time step (GMS stores a separate variogram for each step). This can be accomplished by selecting each time step one at a time using the Time step combo box at the top of the Interpolation Options dialog, and creating a new variogram for each time step.
