Since your geometry and the loads have two planes of symmetry, you can use that in the constraints.<br \/>\nUse a plane parallel to YZ that goes through the center of the blocks Split the blocks using that plane and delete one half, keeping the blocks on the +X side.  The cut faces get a Displacement BC of X=0 and Y, Z Free.  That allows you to apply the pressure load on just one side and have a BC to push against.<br \/>\nIt will be convenient to make a plane parallel to the XZ plane that goes through the center of the half blocks and split the blocks again. Delete half again, keeping the 1\/4 blocks on the +Y side.  Apply a Displacement BC on the newly cut faces of Y = 0 leaving X and Z Free.<br \/>\nThere is one DOF left to constrain, which is motion along the Z axis.  This could be achieved by selecting the faces on the +Z side of the quarter blocks and using a Remote Displacement, set Z = 0 leaving the other five DOF Free.<\/p>\n","protected":false},"template":"","class_list":["post-205586","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Yes, you have correctly applied the kinematic mount for the thermal load, but since you want to apply a pressure to the faces, you can&#039;t use three single nodes.
