Export/Load file.txt in OpenFoam
 

Hello,

I am writing a new BC for time varying inlet velocity.
I could write a vectorfield as a text file by following command in the .C file:

#incude <OFstream.H>
.
.
.
Ofstream myfile ("ux.txt.");
myfile << ux << endl;

However, I do not know how to load a text file! is there any way to do it? btw I am new in the OpenFoam programing. Thank you in advance.

Best,
Mehrshad

I found the answers. See below:

#inlcude <IFstream.H>
.

.
IFstream dataStream("ux.tx")
dataStream >> ux;
