can i change BC from wall to patch in groovyBC?
groovyBC can set a variable BC.but can i change type of BC by it at specified time domains?

yes.i supposed patch in blockMeshDict for both of patch and wall in my groovyBC condition.is it possible that this is the source of printStack error when the boundary should be wall at groovyBC?
clearly questioning does "wall boundary" is set by only (U=U of wall,T:zeroGradient,p:zeroGradient)? do these conditions give the patch impermeable property like a wall(suppose fluid laminar for not confusing with wallFunctions? thanks. |

For most practical purposes patch and wall behave the same. Only certain BCs/models (turbulence, radiation, heat transfer) behave differently on them |
thanks.yes Im searching to find the cause of the error OpenFOAM gives.
I had a thread without answer although is irrelevant but i submit it here hoping to get an answer.why in "hConstThrmo" and "specieThermo" two different dimensions for Cp are commented?(J/kmol.K and J/kg.K) could you enlighten me? thanks very much. |
