Parametric structure (batch mode)

[M_free]

Good evening to all,
I just started using ansys for university reasons and is really fascinated by me, but I got stuck on a problem, we come to the therefore.
objective, reproduce in a completely parametric way (then through the creation of a text file) of a structure modeled through beam and shell.the creation cycle I have carried out it in the following way: creation of kp, creation of line, then definition elements and mesh, application of loads and constraints.resolution of the system. .txt is correct does not generate errors however does not result completely parametric.mi spiego.

loads and constraints are applied to specific nodes (defined by the identification number), however to the varying position of the kp varies the length of the lines and then to the mesh you get a number of variable nodes. the identification number of the specific node that interests me therefore varies.

How can I solve this?

ps:if for example the forces apply to kp what changes for the program?

You need to apply forces to keypoints.
The difference between nodes and keypoints is that. create a basic geometry and then create the mesh. If you always apply the loads to the base geometry, you can change the mesh parameters without moving the loads.
The important thing is to put the kpoints in the right places.

I did not understand everything well, but if the number of the keypoint to which you apply the load is always the same (at the change of the parameter), I could recall the keypoint, then the node associated with the keypoint and apply the force in that /load node.

great wave always available! ! ! !

He thinks you create two keypoints and one line between them. then on the line create beam elements by dividing the line into 5 equal parts, the next mesh in 6 equal parts.
between the two mesh the position of the nodes changes, changing the number of elements, while the keypoints always remain in the same position.
the concept is to put the kpoints where you have to put the loads, and obviously at the top of your model, and then meshare with automatic settings.
Obviously keypoints must be associated with the model, otherwise there is no load transfer.
I mean the keypoint can't be in space, it must always be at the top of a line, which in turn is on the edge of a surface is shell elements.

I'm sorry if I answer now, but I've had some exams... thank you so much for the objective help I've got!
