I created a set of 21 time curves to be used as temperature change with time in a Simulation of a transient analysis of steam turbine rotor startup procedure.  I have entered one Time Curve and it really is time concuming and error prone when typing each data point. Is there an easire way, say I already have a table in Excel that has all the data in the format that is required but I do not see any options that will help bringing in the data directly on to each Time Curve.  The file extension of each Time Curve is *.cwcur which is not recognized by anyhting.
