 I have a twisted tube heat exchanger problem. The result by Discovery Live is wrong. I guess the reason is that DL has fidelity upper limit, so that it cannot catch the tiny gap in some place.  <\/p>\n

 <\/p>\n

This is the model, the arrows show the expected flow <\/p>\n

\"\"  <\/p>\n

Discovery Live give a wrong result that penetrate the wall <\/p>\n

 <\/p>\n

\"\"  <\/p>\n

the whole model is a 6000mm long cylinder. Its diameter is 3000mm <\/p>\n

 <\/p>\n

\"\"  <\/p>\n

It has huge number of small structures from 2mm to 10mm. It seems that discovery live does not capture the details enough to give reliable results, even with the highest fidelity. <\/p>\n

 <\/p>\n

system configuration <\/p>\n

 4 GTX 1080TI graphics cards server, each card has 11GB gpu memory. The system has 96GB memory. <\/p>\n

windows 10 64bit, Discovery Live 19.1 <\/p>\n

 <\/p>\n

Anyone can help me on this problem?
