problem with developing new LES solver
 
hi, everyone, I'm a newbie to OpenFOAM, and it gives me only endless pain so far. So please someone put me out of my misery.

I'm tring to play with icoLagrangianFoam and oodles to get a LES particle solver. the new solver compiled ok. However when I try to apply it with the test case provided with icoLagrangianFoam, it failed and said the case is neither 2D or 3D, so LES is not applicable.

Does anyone have some ideal about this problem?

Have you tried running one of the regular LES solvers on that case? (IMHO it should give the same result thus reducing this to a LES-problem)

Which of the test-cases that come with icoLagrangianFoam is the problem. As far as I remember they're both 3D

Thanks for the quick reply, I've tried oodles and it's working. the problems tend to happen when I add EXE_LIBS -llagrangian into the Make/option file. My experience with programming in C++ is limitied and I don't know FOAM that well. Is there any exist LES + particle solver for me to starte with?
Thanks so much.
