    Acu fieldview Legend

    Hello, I want to show contour of temperature in such a way that. Temperature above certain specific limit should be transparent. Ex: If a component showing Temperature max & min is 300"C & 90"C. The contour is set from 100" to 90"C. So, temp above 90"C will show red in colour. But in place of red, I want transparent (Invisible or white). Simply I want to edit contour. And I don't know the procedure

    ACUSOLVE

    Hello, I am working on automobile component i.e. EGR coolar. Here task is to Cool hot gas emitting out from engine and to send back to engine by using coolar i.e. ethylene glycol. EGR coolar has two fluid gas(hot air) & coolant(Ethylene glycol). Each fluid passing from 1 side. It may be parrallel or counter flow. I am getting inputs from customer like this, I am showing you 2 case as follows: CASE 1: Coolant flowing at 90"C @ 1200l/hr @ 2.5Bar-gauge Exhaust Gas at 450"C @ 150Kg/hr @ 2Bar-gauge CASE 2: Coolant flowing at 90"C @ 1200l/hr @ 2.5Bar-absolute Exhaust Gas at 450"C @ 150Kg/hr @ 2Bar-absolute Hence some time I am getting input value of pressure in bar or absolute. I am giving BC like this: At inlet I am defining pressure and temperature and at outlet negative flow I am giving. But I am not understanding how to value of pressure in gauge and absolute?

    Hello, How to get gif animation in ACUFIELDVIEW I know how to form video in Acufieldview, but problem is video I am getting is in AVI. format. Then I am converting AVI. format to GIF and then preparing ppt. But while converting it, croping option is not there. Due to which ppt presentation is difficult. Is there, any another way where I get gif directly with crop option and with good clarity. Please help me. Regards Rajendra Borgwarner Emissions System

    ACUSOLVE

    I am facing problem with boudary layer. When I am not maintaining BLs result is converging easily but showing wrong result. Only55 to 60% accuracy I am getting. When I am maintaining BL, result is not converging. The values are fluctuating so much, Actually modal is EGR coolar and has two flow i.e. coolant & Exhaust gas. In first trail, I solved with no BL, I got 60% accuracy. I got result trendy at very low time step 60, and I solved it for ten days till TS 1000, but result was same. There is no change. In 2nd trail, I am solving with BL at wall seperating coolant & gas. But here, result I am not getting trendy atleast. 300 TS, already completed, still no result. Solver is also very slow. Taking too much time. For each TS it is taking nearlly 20mins. I have attached inp & log file please find it. Please do needful as I wasted nearlly 1 month on it.
