How to export Min or Max temperature time history (same as Tabular Data) at multiple named selections as a csv from Mechanical thermal analysis?

Rohith Patchigolla

Below script exports the Max or Min time history as csv for multiple named selections (say T1 and T2) in the analysis solver directory.
