Hi EveryOne,

I am working on a simple 3-D model to simulate particle flow through a rectangular domain. I have initially simulated it using laminar pisoFoam and no using its velocity field to simulate the particle flow.

But on running icoUncoupledKinematicParcelFoam, I am getting the following error. I have attached a snap-shot of the error. I am new for this solver and am unable to understand. Please help!

Quick answer: "sigsegv" https://en.wikipedia.org/wiki/Segmentation_fault - is a segmentation fault due to a bad access to memory.

Can you please provide a test case?

Thanks! I have solved that problem. Presently I am working on using a modified icoLagrangianFoam Solver. Actly I am using adjustable time step. After making all the required modifications as I am using wmake I am getting the following error:

Can anybody please suggest how may I solve this problem?

Can you post full error message. Your post only shows warnings and there is nothing to worry about above warnings about unused variables in my opinion.

Please check the last 2 lines in the previous post:

icoLagrangianFoam_new.dep:721: recipe for target 'Make/linux64GccDPOpt/icoLagrangianFoam_new.o' failed
make: *** [Make/linux64GccDPOpt/icoLagrangianFoam_new.o] Error 1

after this the compilation stops in between. I am also attaching the files if required.

Quick answer: I've finally managed to take a quick look into this. The complete output from wmake was this:

make: *** [Make/linux64GccDPOpt/icoLagrangianFoam_new.o] Error 1

Therefore, the specific error is this:

icoLagrangianFoam_new.C:53:20: error: no match for call to ‘(Foam::Time) ()’

Where it refers to this line:

while (runTime())

If we look at the icoFoam solver source code in foam-extend 3.1:

while (runTime.loop())

And with this change, it now builds without problems.

Thanks a lot!!! It worked.
