How do I fix the problem where the temperature gradient during filling process seems invalid?

Hello.

My product is brake drum. I have designed roughly the filling system (ingates, runner, sprue, choke, etc). I used ASTM A48 Grade 35 Cast iron as casting material and the temperature 1305 degree C. picture below is my final design before run the simulation.

I used 'basic setup', the initial velocity is default 1 m/s. the run analysis is default, i only change the element size to 10mm.

So, my problem is the result section. During 'Filling' process, there's no colour gradient whenever i click on replay button on 'temperature' result type. It only appears max temperature from the beginning until it finish, which means there is no gradient temperature (as picture below). It seems like the result is invalid. Therefore, i cannot continue my analysis.

I have watched plenty of videos on youtube regarding steps to use the software. here's one of the tutorial: Altair Inspire Cast Webinar - The Future of Method Engineering with Casting Simulation - YouTube I did almost exactly the same with the video, the different is only the cast material and somehow his result seems run well. below is his result:

So I would like to seek help from the community regarding my problem. Your help is highly appreciated. Thank you.

           Change lower temp to 600
