It concerns the use of Fourier series to generate the 2D BFC grids. It is wholly focused on calculation of grid corner coordinates. Therefore, no other actions are supported by input data. It also differs from the previous examples in being arranged as unsteady problem: at each time moment the new BFC grid is PLANTed and dumped into specified file to be viewed by PHOTON.

All together they provide the calculation of cartesian coordinates for cell corners of the grid fitted the zig-zag channel of 2m width and 6pi length, as can be seen by PHOTON. The grid is uniform in both direction. The generation is made at the first sweep of the first time step. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< 2. 2D periodically broken channel ------------------------------- REAL(AA,ALFA,TWOPI) TWOPI=2.*PI ** Shape factors AA=0.75;ALFA=TWOPI/12 XC=:LENGTH:/FLOAT(NX)*FLOAT(I-1) YC=8/:TWOPI:*:AA:/:ALFA:*(SIN(0.75)*SIN(XC)+$ SIN(3*2.*3.14159/12)* SIN(3*XC)/9+ SIN(5*$ 2.*3.14159/12)*SIN(5*XC)/25+ SIN(7*2.*3.14159/12$ )*SIN(7*XC)/49+ SIN(9*2.*3.14159/12)*SIN(9*XC)/8$ 1+ SIN(11*2.*3.14159/12)*SIN(11*XC)/121+$ SIN(13*2.*3.14159/12)*SIN(13*XC)/169+ SIN(15*$ 2.*3.14159/12)*SIN(15*XC)/225+ SIN(17*2.*3.14159/12$ )*SIN(17*XC)/289+ SIN(19*2.*3.14159/12)*SIN(19*XC)/3$ 61)+ 2.*ZWLAST*FLOAT(J-1)/FLOAT(NY) ZC=ZWLAST*FLOAT(K-1)/FLOAT(NZ) IF(ISTEP.EQ.2.AND.ISWEEP.EQ.1) The above three statements perform the corresponding functions for the generation of the uniform grid fitted the periodically broken channel. It is made at the first sweep of the second time step. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< 3. 2D corrugated channel ------------------------ XC=:LENGTH:/FLOAT(NX)*FLOAT(I-1) YC=FLOAT(J-1)/FLOAT(NY)*(1/3.14159+$ 0.5*SIN(XC-3.14159/2)- 2/3.14159*(COS(2*(XC-3.14159$ /2))/3+ COS(4*(XC-3.14159/2))/15+$ COS(6*(XC-3.14159/2))/35+ COS(8*(XC-3$ .14159/2))/63+ COS(10*(XC-3.14159/2))/99+$ COS(12*(XC-3.14159/2))/143))+ 2.*ZWLAS$ T*FLOAT(J-1)/FLOAT(NY) ZC=ZWLAST*FLOAT(K-1)/FLOAT(NZ) IF(ISTEP.EQ.3.AND.ISWEEP.EQ.1) At the first sweep of the third time step the generation of the last grid of the series is made governed by above formulae. <<<<<<<<<<<<<<<<<<<<<<< Comment ends <<<<<<<<<<<<<<<<<<<<< PLANTEND ************************************************************ Group 1.
