Nodes associated with keypoints

Nodes associated with keypoints

Nodes associated with keypoints

(OP)
Hi there,

I have a keypoint in space and I want to put a node in its place and associate the new node with the keypoint.
This is usefull for later NSLK operations and loading of the solid model.

Anyone any idea how to do this? NKPT does not associate the node and KMESH needs a one-node element (MASS21?), which you can't delete.

Thanks and Regards,

RE: Nodes associated with keypoints

Hello,

you can only associate geometry (kp,line,area,volu) with nodes and elements if are using kmesh,lmesh,amesh or vmesh to automatically generate nodes and elements onto the geometry.

NSLK will not work if you manually define a node on the same location of a keypoint. In such a case use node(nx(kp),ny(kp),nz(kp).

Regards,
Alex

Yes thanks Alex, so I figured. I used the KMESH command for linking the node to the keypoint. And so I needed a one-node element (MASS21) to be able to define the one-element-one-node-mesh. After this I used that node to manually create the element I need (PIPE16).

Problem is that I am not able to delete the MASS21 element because it "is linked to the keypoint". If I KCLEAR the keypoint it looses the association with the node in the PIPE16 element again.
