Greetings
I am new to OpenFOAM and I am simulating the flow through canopies. The version of the OpenFOAM I am using is V3.0.1, and the solver I use is pisoFoam. The B.C. sets inlet|outlet|front|back U cyclicAMI p cyclicAMI lowerWall U fixed 0 p zeroGradient upperWall U symmetry p symmetry (lowerWall -- red outlet -- green back -- blue in the attachment) I put all cyclic boundaries inside one processor by using this in decomposeParDict Code:
method scotch; preservePatches (inlet_ outlet_ front_ back_); Code:
momentumSource1 { type vectorSemiImplicitSource; active yes; vectorSemiImplicitSourceCoeffs { selectionMode all; volumeMode absolute; injectionRateSuSp { U ((1.34 0 0) 0); } } } I am not sure what caused this problem. I tried to use this to create inlet flow Code:
momentumSource { type meanVelocityForce; active yes; meanVelocityForceCoeffs { selectionMode all; fieldNames (U); Ubar (1.34 0 0); } } I am wondering what I did wrong on the configuration of the simulation, any suggestion or idea will be appreciated! Thanks in advance! Best Regards Ben |
