Hey
I am trying to introduce a new heat transfer model in dieselFoam tutorial located in $WM_PROJECT_USER_DIR/src/lagrangian/mydieselSpray/spraySubModels/heatTransferModel/ And in this newheatmodel , there is only one change with respect to RanzMarshall model that I want to calculate the nusselt number by using the formula Nu = Nuo log (1+Bm)/Bm where Bm is mass transport number calculated by Bm=(Xs-Xf)/(1-Xs) and Nu0 is nusselt number as calculated in RanzMarshall. So, now for this I have to introduce Xs and Xf in newheatmodel.C and newheatmodel.H. I have made the following changes to newheatmodel.C scalar dieseheatmodel::relaxationTime ( const scalar liquidDensity, const scalar diameter, const scalar liquidcL, const scalar kappa, const scalar ReynoldsNumber, const scalar PrandtlNumber, const scalar Xs, const scalar Xf, const scalar m0[i] ) const { scalar lgExpr = 0.0; scalar Xratio = (Xs - Xf)/max(SMALL, 1.0 - Xs); if (Xratio > 0.0) { lgExpr = log(1.0 + Xratio)/Xratio; } scalar time = liquidDensity*pow(diameter, 2.0)*liquidcL/(6.0*kappa*lgExpr*Nu(ReynoldsNumber, PrandtlNumber)); time = max(SMALL, time); return time; And the changes to newheatmodel.H are:- scalar relaxationTime ( const scalar liquidDensity, const scalar diameter, const scalar liquidcL, const scalar kappa, const scalar ReynoldsNumber, const scalar PrandtlNumber, const scalar Xs, const scalar Xf, const scalar m0[i] ) Also I have made certain changes in heatTransferModel.H located in $WM_PROJECT_USER_DIR/src/lagrangian/mydieselSpray/spraySubModels/heatTransferModel/heatTransferModel/ Virtual scalar relaxationTime ( const scalar liquidDensity, const scalar diameter, const scalar liquidcL, const scalar kappa, const scalar ReynoldsNumber, const scalar PrandtlNumber, const scalar Xs, const scalar Xf, const scalar m0[i] ) const = 0; And certain changes in setRelaxationTimes.C located in $WM_PROJECT_USER_DIR/src/lagrangian/mydieselSpray/parcel/ And the changes near line 164 are:- for(label i=0; i<Nf; i++) { tauHeatTransfer = sDB.heatTransfer().relaxationTime ( liquidDensity, d(), liquidcL, kMixture, Reynolds, Prandtl, Xs[i], Xf[i], m0[i] ); } When I compiled mydieselSpray library , it properly compiled but when I run my case, it showed an error:- cfd@linux-bw7o:~/OpenFOAM/cfd-1.6/run/decane_heatmodels/decane_6_diese> mpirun - np 4 mydieselFoam -parallel > log & [1] 20041 cfd@linux-bw7o:~/OpenFOAM/cfd-1.6/run/decane_heatmodels/decane_6_diese> [2] #0 Foam::error:rintStack(Foam::Ostream&) in "/home/cfd/OpenFOAM/OpenFOAM-1.6/lib/ linux64GccDPOpt/libOpenFOAM.so" [2] #1 Foam::sigFpe::sigFpeHandler(int) in "/home/cfd/OpenFOAM/OpenFOAM-1.6/lib /linux64GccDPOpt/libOpenFOAM.so" [2] #2 ?? in "/lib64/libc.so.6" [2] #3 Foam::dieseheatmodel::relaxationTime(double, double, double, double, dou ble, double, double, double) const in "/home/cfd/OpenFOAM/cfd-1.6/lib/linux64Gcc DPOpt/libmydieselSpray.so" [2] #4 Uninterpreted: [linux-bw7o:20047] *** Process received signal *** [linux-bw7o:20047] Signal: Floating point exception (8) [linux-bw7o:20047] Signal code: (-6) [linux-bw7o:20047] Failing at address: 0x3e800004e4f [linux-bw7o:20047] [ 0] /lib64/libc.so.6 [0x2ba3a6f77bd0] [linux-bw7o:20047] [ 1] /lib64/libc.so.6(gsignal+0x35) [0x2ba3a6f77b45] [linux-bw7o:20047] [ 2] /lib64/libc.so.6 [0x2ba3a6f77bd0] [linux-bw7o:20047] [ 3] /home/cfd/OpenFOAM/cfd-1.6/lib/linux64GccDPOpt/libmydies elSpray.so(_ZNK4Foam14dieseheatmodel14relaxationTi meEdddddddd+0x11b) [0x2ba3a5d3 26ab] [linux-bw7o:20047] [ 4] [0x7fff07519410] [linux-bw7o:20047] *** End of error message *** -------------------------------------------------------------------------- mpirun noticed that process rank 2 with PID 20047 on node linux-bw7o exited on s ignal 8 (Floating point exception). -------------------------------------------------------------------------- cfd@linux-bw7o:~/OpenFOAM/cfd-1.6/run/decane_heatmodels/decane_6_diese> [1]+ Exit 136 PLEASE SOMEBODY HELP ME.

I THINK YOU SHOULD STOP USING CAPS!!!
... and then remove the dependency of -ldieselSpray for dieselFoam in the Make/options-file. It looks like you are picking up the original dieselSpray library. |

And when i try my case using RanzMarshall heat transfer model, it is working fine. But when i use newheatmodel, only then it shows the above error.

hey there niklas. i have been working on a post-processor to compute the mean nusselt number in a turbulent free convection flow over a vertical hot plate. i am gradually working my way through programming in OpenFOAM, and i am quite unable to find the cause of the bug that i am getting. it is a fairly short code, do you think you can look over the code for me? thanks
