  1. Hello everyone, I want to do a CFD Simulation without a Wall-Function. The Turbulence wall type is set to None, but I don't know what the ''Activate Auto Wall'' does. Can anyone tell me what it does? I've added a screen shot of the boundary condition settings.
  2. hai, I am doing a tutorial taken from the Altair site which is a bird strike on aircraft wing. while i am doing i had a doubt regarding the boundary condition application. i don't know how to apply boundary condition in radioss. please help
  3. Hello Everyone, I was wondering what constraint, shall i assign for simply support condition (Hypermesh/optistruct) to a beam for modal analysis? Thank you for taking your precious time to reply. - Pramod
  4. Hi , I am doing a transient direct analysis of a 1D rod in optistruct . On one end of the rod there is an axial sinusoidal displacement input. The other end is free. I want to look at the transient solution to this problem. i.e I want to see the travel of the first wave of deformation from the forced end to the free end. How can I set up this kind of boundary condition? regards, Vachan
  5. Hi, In acusolve, which one is the correct setting to present adiabatic condition for surface BC? a-> environment temp. = 25 degree C Temperature BC type = Value Temperature = 25 degree C or b-> environment temp. = 25 degree C Temperature BC type = Flux Heat flux = 0.0 Convective heat flux coefficient = 0.0 Convective heat flux reference temperature = 0.0 degree C c-> environment temp. = 25 degree C Temperature BC type = Flux Heat flux = 0.0 Convective heat flux coefficient = 0.0 Convective heat flux reference temperature = 25 degree C Thanks
  6. Hai all, I am doing a linear static analysis by optistruct, when i try to run there show an error "fixed boundary condition in spc is not supported for linear static analysis" what will be the reason for this error? Please help me to understand the error and its solution. best regards, Dani
  7. 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.
