groovybc and heat flux on wall
2 Attachment(s)
Hi foamers
I used groovyBC as boundary condition for wall of my case.but I have a problem.I modifed the heat flux on the wall but when temperature of the upper region of furnace is still 298K and the outer temperature is 298K too.so I expected to see zero gradient on the wall but there is a flux in paraFoam it show me temprature at walls 0 while the lowest temperature is 298 in my boundary conditions. I attached my case figure. any help would be appreciated. type groovyBc; variables "h=1.12;k=0.065;Tinf=298;"; gradientExpression "h/k*(T-Tinf)"; fractionExprssion "0"; // 0 for neumann boundary condition value uniform 298; regards Mohsen |
no idea!!!!!!!!!!

b) Paraview doesn't know anything about groovyBC so the values it displays on the boundary might be wrong c) for finding problems always use the Cell-values in Paraview. The point values are something it interpolates from the real values and might as well be a problem of Paraview |
