Thanks a lot for your inputs, . With your guidance, I have successfully performed the FEM simulation. See Figures 1 and 2. I have a small doubt in post-processing. I wanted to know how is the force distribution (F) at the knife-edge circumference see fig 3. For this, I have constructed a path along the knife-edge circumference see figure 4. Now I wanted to know how much force is acting on the gasket from the knife-edge tip along this path. I tried with probe force reaction but I cannot able to select that circumferential knife-edge. It will be very nice if you could help me further. I am looking forward to your reply. Thanks a lot once again. nnn
