Find the closest node to a point

luc.laurent
Hi everyone,
 
I am looking for a solution for finding the node of a mesh that is the closest node to a specific point.
Currently, my solution is to export the mesh and writing a specific small code in matlab for doing it but it is not very efficient.
 
Thank you in advance.
 
Best regards

    There is an undocumented function in the utilities, give it try:
    Regards,
    Karl
    e.g::
     
    STRING node_list2[VIRTUAL]
     
    bv_get_closest_nodes_4.get( [0.5 0.6 0.7], 0.05,123, node_list2 )
     
    This should result in that the 123 closest nodes to location x=0.5, y=0.6, z=0.7
     
    So to find the closest node you may want to call:
     
    bv_get_closest_nodes_4.get( [0.5 0.6 0.7], 1.E8,1, node_list2 )
     
    Note that 1.E8 isn't used in this case. The tolerance is only used when max_find=0
