Good morning, I'm analyzing the heat transfer in a fixed-bed reactor (3D geometry). I carried out steady state simulation but now I'm trying to perform unsteady state simulation. I start the unsteady simulation using the results data of the previous steady simulation. How can I visualize the temperature profile of a single point of my domain vs the time? I hope some of you will help me! Thank you for your attention!

1. Create a point at desired location: Surface -> Point 2. Set up surface monitor: Solve -> Monitors -> Surface Click define, select your point and choose temperature.

Thank you very much!!!!! I did what you said but when I opened the define panel I found that I have to choose the Report Type. There are a lot of options (Integral, Standard deviation etc..) so, to obtain the value of the Temperature of the point (which I defined) vs time what is the better option that I have to select? And, can you give me an indication of the value of the Time Step Size that I can put into the iteration panel? Thank you very much for your attention!!!

Report type: Area weighted average or Vertex average ... i think they are all the same since point only checks value at one cell.

Time step sampling interval depends on your problem. I use every 100 time steps.
