Greetings

I was trying initiate a Lamb-Oseen Vortex using funkySetFields command using :

funkySetFields -field U -keepPatches -expression 'U+((pos()-vector(50,47.1,pos().z))^vector(0,0,1))/mag(pos()-vector(50,47.1,pos().z))*(530/(2*pi*mag(pos()-vector(50,47.1,pos().z))))*(1-exp((-1/9)*sqr(mag(pos()-vector(50,47.1,pos().z))))))' -time 0

and it is showing me error.

I am running pimpleFoam model and the domain is a cuboid with uniform meshing. The error is as follows

Create time

Create mesh for time = 0


Time = 0
Using command-line options

Modifying field U of type volVectorField

Putting "U+((pos()-vector(50,47.1,pos().z))^vector(0,0,1))/mag(pos()-vector(50,47.1,pos().z))*(530/(2*pi*mag(pos()-vector(50,47.1,pos().z))))*(1-exp((-1/9)*sqr(mag(pos()-vector(50,47.1,pos().z))))))" into field U at t = "0" if condition "true" is true
Keeping patches unaltered

Can anyone kindly suggest, how to sort out this problem..??

Thanks in advance..

Sorry for the post, I got the solution there is a problem with the vortex equation parenthesis...


But i could not delete the thread, may be it's the settings of the forum.

Sorry again..
