Get all nodes on a outer circumference

Hello Experts,

I am new to TCL scripting and I am from a IT background. I am learning Hyeprmesh and TCL scripting.

My problem is as follows : when one node is selected, I would like the script to select all the nodes on the same circumference.

After this an RBE3 has to be created with the selected nodes.

I saw a similar solution for selecting all nodes on circumference when one node is pre selected , but that was for a simple cylinder. This is a crankshaft tube.

Any help would be much appreciated. Thanks

Hi,

Unfortunately i don't have the solution to help you

But would you share the solution you found working with cylinders ?

If mesh is uniform.. then by selecting 3 nodes its is possible.

-get the center node of 3 nodes

-create plane with these nodes

-find the faces of this component

-select the nodes 'on plane' option

what you say @tinh

Yes i think so. Uniform mesh is a special case, and we need 3 initial nodes

Try reducing to 2: 2 init nodes form a vector, looking for an adjacent node that closest to the vector, repeat one by one will help in case of non-uniform

And try reducing to 1: from 1 node find adjacents and looking for a theesome that form a minimum angle (feature angle along circumference is min, along cylinder axis is max)
