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.
