mrf doesn't work

armand · January 7, 2011, 04:03

hi,
my mrf model does not work, I use multiple frame-implicit method. this is occur when I apply inlet boundary. in the output file there are some "warning 003 (fluid inflow detected)".
but if i modeling my case without inlet boundary no problem with my mrf, mrf successfully modeled.

thank you for your response

if you are just modeling MRF, then you should have 3 regions, region 1 would be where you specify the inlet condition, interface the other end to the upstream of the MRF, and then interface the downstream to the third region where at the end it pressure outlet.

good luck.
