Hello, I want to implement a groovyBC on k field in a form of log law.
The BC is given in the figure attached herewith I have an error when running from the BC Code:
--> FOAM FATAL ERROR: Parser Error for driver PatchValueExpressionDriver at "1.8-9" :"field Hh not existing or of wrong type" " (log((Hh/z0))/log((zp+z0)/z0))*Iamb" Code:
inlet { type groovyBC; variables ( "zp = pos().z;" "Hh = 50;" "Uin = 2.7;" "z0 = 0.001;" "Iamb = 0.2;" "II = (log((Hh/z0))/log((zp+z0)/z0))*Iamb;" "k = 1.5*II*II*Uin*Uin;" ); valueExpression "k"; } Thank you. |

Hi,
My guess is that the syntax is incorrect as it only seems to read the first line. Can you try this: Code:
inlet { type groovyBC; variables "zp = pos().z; Hh = 50; Uin = 2.7; z0 = 0.001; Iamb = 0.2; II = (log((Hh/z0))/log((zp+z0)/z0))*Iamb; k = 1.5*II*II*Uin*Uin;"; valueExpression "k"; } Code:
inlet { type groovyBC; variables "zp = pos().z;Hh = 50;Uin = 2.7;z0 = 0.001;Iamb = 0.2;II = (log((Hh/z0))/log((zp+z0)/z0))*Iamb;k = 1.5*II*II*Uin*Uin;"; valueExpression "k"; } |

Hi, yes indeed the error is in declaration of variables,
I calculated the expression in the valueExpression as follows; Code:
{ type groovyBC; variables "H=50;z0=0.001;vel=2.7;amb=0.2;"; valueExpression "1.5*pow((amb*(log(H/z0)/log(pos().z/z0)))*vel,2)"; } |
