  Hi,
  I am trying to write a code to solve a plate (meshes with SHELL181) which is under pressure and it has initial deformation. I detached the nodes from the mesh (MODMSH,DETACH) and I modified them (NMODIF). How can I reattach them to the mesh in order to proceed to the solution?
  Thank you

  Hi,
  You can try node merge.

  Here is the part where I modify the nodes and then merge them
  Yes I have tried that, but I get the note that zero nodes were merged. Am I missing something?
  Thank you for your answer,

  Hi,
  Can you try increasing the tolerance for the NUMMRG command?

  To be honest I am not sure how to do so. The link sends me to another site, where I have to complete a customer registration, but I have access to ansys from my university.
  Thank you for your time,
