Hi, Is there any way to plot gridpoint group? I know how to plot zone group and zone face group, but cannot find the option for the gridpoint group.

Hello,

Do you wish to plot zones containing zone gridpoints which have been assigned a specific group?

Ideally, would be best to plot only the dots represent the gridpoints belonging to a specific group. If this is not possible, it is also useful to plot zones or faces containing the gridpoints belonging to a specific group. It may be worth re-iterating that I can specify gridpoint group by “zone gridpoint group …”, but cannot find a way to check visually whether it has been assigned correctly.

Hello,

Plotting just zone gridpoints is not an option in the _FLAC3D_ gui. An alternative could be to create geometry node objects at zone gridpoints. It may not be the most efficient approach, but it would work.

You can plot only zones containing certain (grouped) gridpoints. To do this in a plot you need to add a “Zone Group” plot item and add a _Group_ range element.

Select the _Group_ range element, go to the **Attributes** pane, de-select **Not** , in the **By** field select _zone-gridpoint_. Then in the **Entries** field add the name of the zone gridpoint group. In mine it was called Fred:

This will show only the zone(s) that contain the gridpoint(s) with the group Fred.
