  1. What is the difference between them in term of slave and master nordes relative movement?
  2. Hi. I want to be compare the composite analysis and contact surface (freeze) the example is above picture. And I want to check the ERP between 0~3000Hz. and I can get the follow this. (damping material density is 1856.07kg/m^3) The blue line is contact surface(freeze) model, The black line is composite model. why the blue line is more big value than black line abouy twice. why the blue line is more big value than black line. I want to know why two lines are different exactly. contact_al_dam.fem contact_al_dam.pch compostie_test_revised.fem compostie_test_revised.pch
  3. Hello every body here, this forum is really helpful, just keep the good work ! I know that in general contact problem is non linear BUT i would like to know if it is possible to perform "linear analysis" with optistruct when the contact interface type is set to freeze or tie ? Thanks a lot. Best regards, GAYE
  4. Hi Guys, I have been trying to analyze (static linear) the effect of pressure on an assembly of 2 disks. They are of different materials. The bottom surface of the bottom disk is fixed and pressure is applied on the whole top surface of the top disk. I have tried using freeze contact and also tie but I am only getting stresses on the top disk in the results in both cases. The deformation seems weird because the top disk deforms through the inside of the bottom disk and I get an ice-cream cone like shape. ( I did refer to RD-2100 tutorial for solids in contact) I would really appreciate any help with this. I am a new HW user. Thanks!
