 July 19, 2009, 08:35 Can CFX user function be used to extract wall pressure and face element area? #1 New Member   Join Date: Jul 2009 Posts: 16 Rep Power: 9 Hi all: I am now doing some work about FSI. I want to extract the wall element area and its cooresponding static pressure. Can user fuction be used to do this work ? Thank you for your attention!!

 July 20, 2009, 03:42 what about the area and pressure of vertices " #3 New Member   Join Date: Jul 2009 Posts: 16 Rep Power: 9 Hi , thank you very much for replying this topic. I want to extract the coordinate, area and pressure of all the vertices of a wall boundary. Is the CEL capable to do this work ? Thank you !

 July 20, 2009, 22:32 The coordinates and force act as loads #5 New Member   Join Date: Jul 2009 Posts: 16 Rep Power: 9 Hi, In case that all the coordinates, areas and pressure of a wall boundary are exported, they can be used to calculate loads. Then the loads will be assert on a structure to calculate its deformation. Thank you for your attention
