I am applying displacement as prescribed motion at all nodes at bottom plate of a tank in Y direction. I then applied *BOUNDARY_SPC restricting the movements in X and Z and rotations in all three directions. The card looks like below:<\/div>\n<div><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/05-03-2024-1709667817-11.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/05-03-2024-1709667817-11.png\" alt=\"\"><\/a><\/div>\n<div>&nbsp;<\/div>\n<div>&nbsp;<\/div>\n<div><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/05-03-2024-1709667841-12.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/05-03-2024-1709667841-12.png\" alt=\"\"><\/a><\/div>\n<div>&nbsp;<\/div>\n<div>\n<div class=\" Dyb9Ge\" aria-hidden=\"true\">\n<div class=\"tGPUJe\">&nbsp;<\/div>\n<\/div>\n<div class=\"X7AGAf\">\n<div class=\"UZ2tvc\">\n<div class=\"NcB7hc\">&nbsp;<\/div>\n<\/div>\n<div class=\"ptW7te\" role=\"region\" aria-labelledby=\"c214\">\n<div>I found some online resources which states, &#8220;you shouldn&#8217;t need both *Boundary_prescribed_motion and *Boundary_spc. You should just be able to create a node set and use *boundary_prescribed_motion_set where you will reference the node set and use your current settings. The DOF in the boundary prescribed motion card will restrict motion to only that direction so you don&#8217;t need spc.&#8221;&nbsp;<\/div>\n<div>&nbsp;<\/div>\n<div>But when i don&#8217;t use&nbsp;*Boundary_spc&nbsp;then the model got aborted. However, if I use&nbsp;*Boundary_spc&nbsp;restricting the movement in other two directions (X and Z including rotations in all three directions), then the model works fine.&nbsp;<\/div>\n<div>&nbsp;<\/div>\n<div>Please provide me some insights on this.
