  I am working on model where bearing rollers are replced by non linear springs ( 1 roller is replaced by 5 springs) and I would like to make spring connection region as rigid. (somthing like in the fig. red strips ) is it done in meshing or geometry?

  If you define a connection of bearing type in ANSYS workbench, then there is an option to have that face where the bearing is on as rigid.
  
  See the tutorial below:

  Hi, thank you for the reply, in my model , I replcaed rollers with non linear springs , roller characterisitc is shown by springs . I am not sure I should apply bearing type connections.
  
  Each roller is alreday replcaed by 5 springs

  If you want springs then in the tutorial above, and at the end, they apply spring connections (with rigid behaviour at the connecting face) - hope this helps

  yes I checked whole tutorial , there was option for ridig connection , but it is only available in remote connection mode not in direct connection mode , I have total 700 springs in model which cannot be generated(cannot use object generator) by remort connection option.
  
  I made one spring by direct attachment then used 'object generator' to multiply it .

  Do not know that one, not sure. Perhaps someone else has some ideas

  Alternatively if you do not care about these areas which you obviously don't since you want them to be rigid, create surface bodies on these areas (red patches) and set the Young's Modulus for them say 10 times higher than steel (use say a couple of mm thickness).

  @jj77, here is a tutorial on the Object Generator.

  Thanks for that but I am not looking for any info, if you though could see the original post and see if you can help that would be appreciated for sure by

  moeenkhurram,
  
  A possibility is to apply CERIG for all the nodes you would like to be rigid. You could create the 700 springs in APDL via scripting with *DO loop and E after defining the spring element properties to connect individual nodes to spring elements.
  
  Kind regards,
  Jason
