Saurabh-Tatyaso.Nikam@stu is on a distinguished road
Hey guys, I am new to openfoam and programming, so please neglect my programming skills.

Problem Statement:

A 3D block with (1 x 1 x 0.01)m dimensions. Assuming it 2D.
I want to move my heat source on top surface in X direction. Actually instead of heat source I was planning to assign a temperature value to cell. Now thing is i want to move this cell with constant temperature in X direction with respect to time. for eg : at t=0 sec, X= 1st cell ; at t=1 sec, X=2nd cell ; at t=3sec, x=4th cell and so on . Note: temperature remains constant for all time instants and position.

I have tried to use codedFixedValue as i can grab time and position. But i think i am making some mistakes with code. Can you guys help me to sort it out? Also the thing is I have to stick with laplacianFoam only. Also please tell me will this method work for me or i can use something else?

Following is my code. I know I am doing wrong stuff, i hope you get the idea what exactly i want to do.

Code:
codedPatch
    {
        type            codedFixedValue;
		value			uniform 0;

		name    		codedPatchBC;  

		code
		#{
		    
		    const scalar pi = constant::mathematical::pi;
		    const fvPatch& patch = this->patch();
		    const vectorField& cf = patch.Cf();
		    const scalar t = this->db().time().value();
		    scalarField& field = *this;
		    forAll(cf, i)
		    {
                        scalar x = cf[i].x();
                        for (x=0,t=0; x<0.5 && t<0.5; x++, t++ )
                        {
		    	field[i] = 500;
                        }
		    }
		    
		    
		   
		
		#};

    }
Thanx in Advance
