Hello Adrian

Source arrays are defined by these parameters:

You will be able to modify these properties in the optimization but you won't be able to move one source individually. So I am afraid you would have to create separate sources if you want them to move separately. 

From your message, it seems like this is not a good option so I'd like to get a better idea of what you are doing. What kind of source are you using? Is it the Source Object ? With Source Objects, you can  have multiple sources using the same parent object.

Another option would be to keep working with an array and then if a source needs to be switched off, you could for example add an absorbing detector polar around. Then you could add a new source that can be moved.

I have also looked at the array object but unfortunately you can't create a source object or a source imported from an array object.

I don't have a great workaround but if you can share more details that may help.

I have attached a simplified file to discuss.

Feel free to open a case if you do not want to share details with the whole community.

Thank you.

Hi Jo,

Thanks for your post!

In this case, if you would like to move the sources individually, and not in a regular array, and you also need to model the case of the lamps, I think the best workaround would be to use an individual source object for the lamp itself, using the same parent object for every lamp, and to use a Boolean CAD object to model the case for each lamp individually again. For the Boolean CAD objects, you may use the same imported and exploded assembly for every lamp and position them relative to the individual source objects. The local coordinate system of the resulting Boolean CAD object will be the same as the local coordinate system of the first object listed in the boolean Control String, while the global object position and orientation is set by the object position and tilt parameters in the same manner as all NSC objects. In this way, you can model every lamp with only 2 objects, one source and one boolean, and you only need to do the import and explode the CAD assembly once for the whole system.

You may find more information about the Boolean CAD object type in the Help file at:

The Setup Tab > Editors Group (Setup Tab) > Non-sequential Component Editor > Non-sequential Geometry Objects > Boolean CAD

and in these knowledgebase articles:

Additionally, you can hide the some lines in the NSCE editor to make it more readable:

I hope this helps, but if you have further questions, please let us know and we will be happy to help!

Hi

The table didn't show in the previous post, so here it is here.
