When a simulation is running, in the past I could see the (progression of the Velocity view in Solution Fields). Now I seem not able to view it, see below screen shot: ![afbeelding.png]() ![Processorparts](https://www.simscale.com/forum/uploads/default/original/3X/3/0/301e978ed6daeb0107bc05154d14f71a5e04e86a.png) It looks (?) to show the processor regions? I seem not able to see the Velocity data (except after the simulation has finished or stopped). What do I do wrong?

Hi @molen_victor, It seems like everything works fine for me, I could see the velocity field clearly (see attached image). Are you also able to see the velocity field now? Thanks!

I can see the velocity field AFTER the simualtion has finished (or chanceled), but not during. So I just started up a simulation (name: check if I can see velocity field when simulation is running ) and see if I can see the velocity field (it runs for some 5 hours, I think, so perhap you can also see it). ---

It is still running (it is at 30% after 5h: "[https://www.simscale.com/workbench/?pid=2941753789023552936&rru=12a86201-0226-4d51-8e49-f5ecb6aad864&ci=1c40dadd-4725-4f52-ab94-5f92bf8d7d81&mt=SIMULATION\_RESULT&ct=SOLUTION\_FIELD"](https://www.simscale.com/workbench/?pid=2941753789023552936&rru=12a86201-0226-4d51-8e49-f5ecb6aad864&ci=1c40dadd-4725-4f52-ab94-5f92bf8d7d81&mt=SIMULATION_RESULT&ct=SOLUTION_FIELD)). Anyway I am not able to see the velocity of other things [only something that looks that processor volume division [but not sure]). ![afbeelding](https://www.simscale.com/forum/uploads/default/original/3X/e/a/ea7eb26d5ad35e175315574efb8e2b3a0deedc00.png) ---

It runs NOW for 5 hours (at 55% of the simulation) and still no Velocity or Pressure coloring, or. ---

The simulation is till running (9hours and it is at 95%). Still only the processor view; o speed colors. ---

Simulation has now ended, and I can see the velocity colors… ---

So still the problem that I see no Velocities, of Y-axis or other things’ colors during simulation. A great miss. Why is this behavior changed since ???, as I saw in the past during a simulation these colors. ---

@BryanArsenio can you help me understand this behavior? Thanks. ---

This was an unintended behavior that should already be fixed at this point, thanks for bringing this up. ---

Thanks, I will check in the coming days. ---

It is indeed working as in the past. THANKS.
