Hello,
I am trying to model a seal with penetration with Ansys Mechanical. I have extensive CFD knowledge, but am somewhat struggling with this FEM problem. <\/p>\n

I wanted to simulate the seal with small changes in its size by scaling plus minus 10% to check the effects of tolerances. I am able to solve the original size by using penetration and interference modelling to find out contact pressures. When i try to use the same setup for the scaled up version, i notice high element distortion, which only seems to be resolved by reducing the mesh density. This solution, however, is not satisfactory, as there are fewer nodes to detect contact and my model still has penetration. <\/p>\n

How should i go about resolving such high amounts of penetration?<\/p>\n

Your help is much appreciated \ud83d\ude42<\/p>\n","protected":false},"template":"","class_list":["post-293596","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
