Divergence after high number of iterations -- CFD Online Discussion Forums

November 14, 2013, 05:22	Divergence after high number of iterations	#1
guserik New Member erik gustafsson Join Date: Oct 2013 Posts: 19 Rep Power: 12	Hello I got a really frustrating problem. I have established a procedure for simulating conjugated heat transfer between fluid and solid with chtMultiRegionSimpleFoam. My models have always worked but now when i have a really fine model everything crash after around 600 iterations. Until this the solution converge good and the all residuals are less than 0.001. Is there anyone who knows how to solve this problem?
