Capturing Multiples scènes in a time step fails
 
Hi, here is my problem, i want to capture 3 differents scene in a time step, the first one is captured correctly but, in the two others the grid is translated for an unknown reason.
(See the attached pictures)

The pressure scene : (which is fine because its the first selected to be captured)

The turbulent kinectic energy where the grid is translated

The Volume Franction where the grid is also translated

My first thought would be, the plane section are not identical. There is no reason why ccm+ should calculate a different section for the same mesh at the same position just due to a different scalar to display (which is pretty much just a colored overlay).
When you create one plane section and create three scenes containing this single plane section, the mesh has to be displayed identically.

Well it's a 2D simulation, so there is only one section. It's not a section generated with the "derived part" menu. Also i took care to "store view" the first scene then to "restore view" the others scences to be sure that it was going to capture the same images...

Okay, I'm sorry. How did you get that grid? I think, it's not the grid, the scene moved relative to the grid.

You can add a grid via the annotation menu, but first you will have to setup the grid by going to tools-->annotation-->add anotation-->grid
Hope this helps
