time series BC

Hi,

I have a square 3D model with hydraulic head boundary conditions on the edges.
My hydraulic head BC is not constant along the edge, I have created a dat file that links the hydraulic head to each node by linking the node numbers to each other.
Now i want to run model in transient state. the value of the hydraulic head at each node has changed. My da file has now a column that points to the node number and 3 different columns that point to the hydraulic head at different time steps. Is it possible to link the change in hydraulic head for each node automatically, direclty from the dat file ? If yes, can you please show me how. (ie: I want to assign the value in each column to a time step, for all the nodes in my file).
Thank you

I think you need to create "Time Series" data for each node
Then have another shapefile/ excel table to include the times series id column.
Then go add the shapefile/ excel table to your Maps panel.
And then link to Parameters(s).... by right click your shapefile/ excel table
In the "Parameter Association" window, you link you times series id column to your Hydraulic-head BC
And in the "link type", you change that to "time constant data" to "time-varying (time seies id)"
