Hi, I’m new here and I’m starting to use the program.
I recently started a project to see how the currents of a river and its speeds are managed, so I do the simulation in OpenFoam and it is successful when I pass it to ParaView, I run it but only the second one looks normal from there the whole river It turns red, I don’t know what the problem could be or if it would be directly from the programming.
Thank you very much if someone knows something and could help me.

Maybe you are looking for “Rescale range over time” ?

What changes is the color range, I don’t know if it’s what you mean or where I could see the range over time ?
