Hi All,
I'm simulating a simple 'valve bc' to allow a tube to purge after exhausting its high pressure gas. I have used a execute on demand UDF and scheme file which allows the switch between a wall and a pressure inlet once the pressure inside the tube gets below a desired pressure. When i run the simulation I get a segmentation fault the iteration after the wall switches to pressure inlet. When i call the files/macros manually I have npo issue and it runs fine. Likewise if i continue to run the case after the fault it works as desired. I am a little stumped as to why, so if someone can shed some light i would appreciate it! peace |

Solving my own question...make sure the updates are set to the same interval as you call the udf/scheme. Always love a simple answer.lol
