I found in creatFields.H file of interfoam (It was commented)

// Read the data file and initialise the interpolation table
interpolationTable<vector> timeSeriesAcceleration
(
runTime.path()/runTime.caseConstant()/"acceleration.dat"
);

i wanted to input an acceleration file in openfoam. So i simply uncomment it and added interpolationTable.H header file. It compiled without error.

when i made a acceleration.dat file and kept it in constant directory and run the case the case runs. but the problem is it don't solve for acceleration according to the acceleration specified in acceleration.h..... Instead it just solves as acceleration specified in g file. if i remove g file it gives an error. Please help me if there is something else to be specified in solver to input acceleration.dat file.
