    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?
