linear vs non-liniear analysis structural

    • aminuddin setyo

      hello, i wanna do soem linear analysis on my model

      how to setup linear analysis?
      because it seems that when I use the default setup (program controlled), it performs a non-linear analysis my model has several bounded contacts and 1 frictional contact,
      so should I disable the stiffness update to never, then disable the non-linear effect on the geometry tree?
      on the other hand I have also disabled large deformations Thank You

      Frictional contact is nonlinear.

      If you change the Frictional contact to No Separation, that is a linear contact and then you can solve as a linear model.
