I am simulating a cfd simulation where gas fills a chamber transiently and when pressure builds beyond a value, say 15 bar, one of the solid surface (which is meshed as sold valve) that separate the outer fluid domain with the chamber opens up. So i would like to create a udf where based on pressure it will switch from wall to interior (and both shadow and main surface merges) and solid_wall cell zone would become fluid zone type and simulation continues. Any pointers to udf would be helpful. Is there a quicker way to achieve this goal. Kindly let me know.
