Sindibad is on a distinguished road
Hello everyone,

I have recently been attempting to create a case using HELYX-OS 2.4.0 and OpenFOAM 4.1. In the case, I am modelling flow around a scaled down building (CAARC) with LES. However, I was interested in implementing a parabolic velocity profile using the power law.

In order to do this, I must replace part of the code contained in the U file that is within the 0 folder which is within the case file. After adding some code into the controlDict file to measure pressure at certain locations as well as other data like drag and lift coefficients, the case was running fine using pimpleFoam. However, after replacing the bit of the code I obtain the following error:

Code:

}


I have not been able to find any errors which are the same elsewhere. Can anyone help me understand why this error is coming up? I would be greatly appreciative if anyone could help me in understanding how to fix this error.

I have attached a link with all the files inside if they are required to be seen.

The case file is named CAARC_LEs_3Dcfdonline (the system file contains the modified controlDict file)
The folder in the google drive also contains the modified controlDict by itself, as well as the U file which I have been inserting in the 0 folder of the case file.

Again, I would appreciate any input on how to fix this error.

Many Thanks!
