Rubber seal deformation

We need to find out how much force is needed to press a silicone rubber "lip seal" against an uneven surface for it to deform for a full seal. Tell me WHY you and your available tools are the best choice for this task... Applicants with general self-focused bla bla bla will be ignored...I don't care if you designed a space shuttle or were the best student at MIT. Automated replies will also be ignored.... I want to know how you will solve my seal problem. I will provide the necessary 3D models
