Hi all,I'm a beginner in FEA and got a problem regarding nodes.

SUMMARY

The discussion focuses on using APDL scripting in Finite Element Analysis (FEA) to create nodes along a line, specifically an arc. The recommended approach is to utilize the LMESH command for automatic meshing, which generates nodes and elements along the specified line. For more precise node placement, users can employ line division commands to create keypoints, followed by the NKPT command to manually define nodes and the E,n1,n2 command to create elements between them.

PREREQUISITES
  • Familiarity with ANSYS APDL scripting
  • Understanding of Finite Element Analysis (FEA) concepts
  • Knowledge of meshing techniques in FEA
  • Basic command structure in ANSYS software
NEXT STEPS
  • Research the ANSYS LMESH command for automatic meshing
  • Learn about line division commands in APDL for precise node placement
  • Study the NKPT command for defining keypoints in ANSYS
  • Explore the E,n1,n2 command for creating elements between nodes
USEFUL FOR

This discussion is beneficial for beginners in Finite Element Analysis, particularly those using ANSYS software, as well as engineers and analysts looking to enhance their skills in node creation and meshing techniques.

Hi all,

I'm a beginner in FEA and got a problem regarding nodes. Can you split a line into a number of nodes using APDL script? Then a force should be applied as these nodes using F. The line is and arc.

Thanks in advance

Sure, the easiest way is to simple mesh the line using the LMESH command. That will create nodes and elements along the line.

If you want to more specifically place the nodes, then you can use the line division commands. I'm not sure of the exact command, but you can divide a line in a few different ways. This will create keypoints at each of the line endpoints. From there, if you want to create the nodes and elements by hand, you can place nodes on the keypoints, using NKPT and then join each node by simply issuing the E,n1,n2 create element command, or by simple meshing again (which I believe will automatically place nodes on keypoints).
