Surface / plane intersection and move closest node of the surface to the intersection

Altair Forum User

Hello, 

i am looking for a mesh modification with TCL. Let me present my concern.

- i have a geometry i don’t want to modify.

- I want to create multiple plane at different Z location

- I want to determine closest node to the intersection surface / plane and move the nodes to this intersection following the surface curve.

does anybody has any clue to do that with HyperMesh functions ?

thanks in advance

best regards

Could you show some screenshoots?

can you do it with GUI? why you need to do it by TCL?

Sorry, I didn't see you replied me.

I don't want to use the GUI, only TCL to do it automatically.

I took another way that is to calculate the min distance between nodes on lines and the objective.

But, I am stick on the node selection : 

set Line_Peau_Sup_Milieu ' 1 5 135 150'

eval *createmark nodes 1 'by lines' $Line_Peau_Sup_Milieu 

 

Hypermesh does not found any node.

 

Do you have an advise. I don't see ma mistake.

Thanks a lot

Best Regards

I also tested without success : 

set Line_Peau_Sup_Milieu {1 5 135 150}

Should be

eval *createmark nodes 1 {'by lines'} $Line_Peau_Sup_Milieu
