Hello, in my simulation, I am trying to use some telemetry data formatted into an Excel spreadsheet. The first column has time data and the second has corresponding Wattage from a heater. Under Global Definitions, I made an Interpolation Function and imported the data with these settings:
Function name: Q_t
Position in File: 1
Interpolation: Nearest Neighbor
Extrapolation: Constant
Plotting this results in the same plot I'd see in Excel or MATLAB, so I'm assuming COMSOL recognizes the data. However, when I try to use "Q_t" later, it gives me a warning and "Unknown Variable Q_t." To be thorough, I have Heat Transfer > Heat Flux, where total heat flux is defined by Q_t![]()
![]()
![]()
![]()

Function name: Q_t
Position in File: 1
Interpolation: Nearest Neighbor
Extrapolation: Constant
