turbulance model
Hello,
In my mesh domain gives iteration didnt converge. I am using 5 mesh block and my rotor inside 5th mesh block. My simulaton's Physics are - Grativy and non-inertial reference frame gravity is z= -9.81 - Moving and simple deforming objects gmo model activing and moving object option is implicit - viscos and turbilance Rng model I tried lots of things and that problem isnt about mesh domain or cell sizes, but I didnt find why simulations solvers giving iteration didnt converse. - I tried history data, short print and long print intervals = 1e-05 or 1e-07 and selected data interval = 0.1 - i tried change mesh cell size for lots of numbers And mine problem I think about inner mesh structure no comfirmity with inner geometry or y plus value problematic turbulence wall boundary no condition satisfied. I need your opinions about thats parameters. 1- How can I check which one is selected? rfg turbilance model +swf or rfg turbilance model + enhanced 2-I used impicit and which one better implicit or explicit? if your ansver is explicit, Why? And What is the best option for explicit advection? 3- Can I try drop relaxation factor Thank you for your interest |
