I am trying to import some external data as .txt file and I want to interpolate this data to apply it as an initial temperature condition to my thermo-mechanical simulation. The data is divided in multiple columns with x, y, z coordintes and the temperature values in °C. I've read some coumentation and some other threads about interpolating external data, but I am still not able to apply the data correctly, namely my function till has a waning and appears yellow. The first question is: how can I correctly import the data? Please find attached some screenshots of the interpolation function and the initial condition. I also attach the .txt data for your reference.
After importing the data I would like to convert it to kelvin, can I just add a +273 when defining the initial temperature value? precisely I would expect something like: int1(x[1/m], y[1/m], z[1/m]) + 273
