Thank you for your reply. I understand that there is the math to create a plane equation and normal vector, but is there no function in apdl to do the job? And I do not have an even surface (non planar) I require a tangent surface to this point. Any suggestion?

Hi, I do have the coordinate and the node ID of the node on surface. How do I get the surface equation and the normal to acquire the node at a certain depth on this normal vector? Regards

Hi, Thanks for your reply. I am writing snippets in ansys, planning to adapt it for batch analysis to export nodal value. Elements type are generally tet and hex. The point of interest lies beneath a surface node from a known distance and tangent to this surface node. I have tried with *get...

Hi everyone, I'm currently struggling somehow with apdl post-processing to obtain stress of a node beneath a surface Hotspot. This node is lying on a normal vector from this Hotspot(currently with known ID and its coordinates). Mathematically speaking, i will need a tangent surface to this...
