UDF to change BC from Wall to Grid Line -- CFD Online Discussion Forums

February 21, 2006, 10:14	UDF to change BC from Wall to Grid Line	#1
Aaron Smith Guest Posts: n/a	Hello All, I am attempting to model a burst disk in an enclosed tube using a UDF. However, i am unsure on how to change the boundary of the burst disk from a wall at the beginning to a non-existing wall when the pressure reaches a specified burst pressure. If anyone would be able to help me in this matter, it would be greatly appreciated. Thanks in advance. Aaron Smith
