# NODE number lookup

Hi,

I’m making my first model with BRIC elements and I’ve noticed a thing I can’t seem to figure out.

When I create BRIC elements it’s possible to subdivide each edge using the N, N and K option which will introduce a series of new nodes. If I know the coordinate of a node, is it possible to lookup the node number, so I can apply a support condition to that node?

Below is a minimal example illustrating the issue.

The generated nodes get incrementing node numbers, so it’s hard to know what node to add a support condition to “dynamically”.

Thanks in advance, hope someone can help

Hi Patrik,

if you know the coordinates of the node, the easiest way is to look up the node number in result viewer. You can use the filter options to search for the node number with specific coordinates.

Best regards,

You can also add support conditions to a node with sofimsha without knowing the node numbers, for example:
