JP, Your Python program came through garbled. At any rate, I reformatted it and got your (CLC) formula to work. A few suggestions: "CLC" is both a function and a parameter name. This may or may not be a problem, but it is somewhat confusing to reuse that identifier. Are you sure your Jython is properly formatted with correct indentations? You have defined a few functions but have you defined the formula that references those functions? See the video "Creating a Jython Formula" to see what I mean. http://goo.gl/n0Frpb Best, Unidata IDV Support > def CLC(T): temp=noUnit(make2D(T))+273.15 > cc=6.11*exp((17.625*temp)/(temp+243.04)) return cc----------------------def > UL(CLC,T,P): e=noUnit(make2D(CLC)) temp=noUnit(make2D(T))+273.15 > press=noUnit(make2D(P)) r=.622*e/(press-e) ul=2501000*r*9.81/(287*temp) > return ul-----------------------def LL(CLC,T,P): cc=noUnit(make2D(CLC)) > temp=noUnit(make2D(T)) p=noUnit(make2D(P)) h=2501000 r=.622*cc/(p-cc) > a=(h*h*r)/(462*temp) ll=1004+a return ll---------------------------def > LR(UL,LL): ul=noUnit(make2D(UL)) ll=noUnit(make2D(LL)) lr=ul/ll return > lr----------------------------def Apollo(LR,T,DP): lr=noUnit(make2D(LR)) > temp=noUnit(make2D(T)) dewp=noUnit(make2D(DP)) > x=1.1*5280*(temp-dewp)/(9.8-lr) return x > JP Kalb > > On Monday, December 29, 2014 8:45 AM, Unidata IDV Support <address@hidden> > wrote: > > > JP, > > Please provide us with the formulas in question. > > Best, > > Unidata IDV Support > > > Full Name: JP Kalb > > Email Address: address@hidden > > Organization: SJSU > > Package Version: 5.0u1 build date:2014-08-08 16:54 UTC > > Operating System: Windows 7 > > Hardware: Java: home: C:\Users\metr166\IDV_5.0u1\jre version: 1.7.0_51 > > j3d:1.6.0-pre9-daily-experimental daily > > Description of problem: Creating display: Color-Filled Contour Plan View > > NameError: name 'CLC' is not defined > > org.python.core.PyException > > > > I am getting an error in this code however > > CLC is defined as well as the formula which is inputting CLC > > > > ****************** > > Stack trace: > > Traceback (most recent call last): > > File "<string>", line 1, in <module> > > NameError: name 'CLC' is not defined > > > > > > > > > Ticket Details > =================== > Ticket ID: VEO-229733 > Department: Support IDV > Priority: Normal > Status: Closed > > > > > Ticket Details =================== Ticket ID: VEO-229733 Department: Support IDV Priority: Normal Status: Closed
