I am new to OpenFoam and would like to realize a substract between two vector fields.
I have tried to use foamCalc but without success:
"foamCalc addSubtract UL ULMean"Create time
Create mesh for time = 0
--> FOAM FATAL ERROR:
Invalid calcMode: ULMean
Valid calcModes are add and subtract
From function calcTypes::addSubtract::preCalc
in file basic/addSubtract/addSubtract.C at line 229.
If someone have a idea it would be great.
my goal is to calculate the RMS vorticity fluctuation,is somebody know how to do it?
thank you for your help!!
The correct syntax would be something like
A better way to calculate the RMS values, may be to use function objects during runtime: http://www.cfd-online.com/Forums/ope...ldaverage.html
Thank you Bernard I have tried your second solution and it works.
