The calculation method given in this link can no longer be used. The hemispherical elastic material deforms after being pressed by the steel plate. Is there a method to calculate the contact area between the elastic material surface and the steel plate?

Instead of integrating the expression '1', which would give the whole area of a boundary, you can integrate an expression like 'incontact_p1'. This is a boolean variable which has the value 1 where the contact condition is fulfilled and 0 outside. The suffix 'p1' is the name of the contact pair.
