Hi,

When trying to compute the forces and coefficients around a 2d aerofoil section, i get this error message...

--> FOAM FATAL IO ERROR:
expected a [ in dimensionSet
in stream ITstream : C:/PROGRA~1/BLUECF~1/ofuser-of5/run/aero3/constant/transportProperties.nu, line 18, IOstream: Version 2.0, format ASCII, line 18, OPENED, GOOD

I have already tried editing nu in transportproperties into different formats but nothing works.

I have tried both

nu l0 2 -1 0 0 0 0] 1e-05;

and

nu nu[0 2 -1 0 0 0 0]1e-05

[Taataa]

it seems like a typo, it should be:
nu [0 2 -1 0 0 0 0] 1e-05; // change | to [
or
nu nu[0 2 -1 0 0 0 0]1e-05; // add semicolon

if you're using OF 5 you don't have to add the dimension so nu 1e-5; is enough.

Hi,
Same problem, I've tried the solutions above and nothing. The model is running but when I try to run with functions it stops working with this error:

$ icoFoam >log

Which error do you get, if you use the following line?

nu              [0 2 -1 0 0 0 0] 0.1;
