Dear Foamers,
I am currently developing a boundary condition to interpolate values over time and space like the timeVaryingMappedFixedValue patch, but for traction/pressure (tractionDisplacement patch) which inherits the fixedGradient patch. After the interpolation weight (s) is calculated, the timeVaryingMappedFixedValue patch assigns values through this command Code:
00710 this->operator==((1-s)*startSampledValues_ + s*endSampledValues_); On the other hand, the tractionDisplacement BC assigns its values to gadient() as: Code:
gradient() = ( (traction_ + pressure_*n)/rho.value() + twoMuLambda*fvPatchField<vector>::snGrad() - (n & sigmaD) )/twoMuLambda; Best regards, Hisham Last edited by Hisham; September 27, 2011 at 17:32. |
