In 1.5.x, the fan boundary condition allowed a negative pressure jump across a cyclic patch. That is, with something like this for pressure
Code:
{ type fan; patchType cyclic; f List<scalar> 3(0.0 0.0 -1.0); value uniform 0; } However, in 1.6.x & 1.7.x it appears that the jump is not allowed to drop below zero. i.e. in fanFvPatchFields.C we now have Code:
-- snip -- for(label i=1; i<f_.size(); i++) { jump_ += f_[i]*pow(Un, i); } jump_ = max(jump_, scalar(0)); -- snip -- Mike |
