  Hello,
  
  Combin14 is not possible with the non liner spring.
  
  Hence i go with the Combin39 or Combin40.
  
  I have attached the spring rate which i needed. I am trying to simulate the spring solid length behavior.
  
  When i try to use the comment attached... i could not solve the problem when i give the Force as input. and the problem could be solved when i give the displacement as input.
  
  Can any one help me ?
  
  also is there is any method for creating gap elements? ie gap of 5mm should be there .. as soon as gap closes the contact should transfer the full load to other part??

  The COMBIN40 element includes a gap capability.

  Thanks Peter.
  
  I have saw your post on Combin40. i will see the gap elements problem with that

  There are many reasons why a solution will not complete. The spring definition is not enough information to say why the solution failed.
