Unexpected Behaviour with temporal Array Operator

ParaView Support
1

Hi,

I am using the temporal array operator to look at changes between timesteps.

Although I have noticed unexpected behaviour.

It seems like all the fields show values from the previous timestep after applying a temporal array operator, rather than showing the values from the loaded timestep.

Am I doing something wrong, or is this the intended behaviour?

note the colour ramp is showing the same field across, Top Images show before using a temporal array operator. Bottom images show the same slice after a temporal array operator is added.

Hi @SJackson ,

The Temporal Array Operator does the difference between two explicitly set time steps: the ParaView main scene time is not taken into account.

A new feature in the (ongoing) ParaView 6.0 release will allow you to do the difference between current time step and another (usually previous one).

You can try the release candidate: https://www.paraview.org/download/?version=v6.0

Understood - I did find that it works as expected in 6.0

Just for reference I was using the time manager to set the first time step index to the currently loaded step, and the second time step index to the previous. Either way the relative step option in 6.0 negates all that!

Thanks for the response.
