ERROR Floating point exception (core dumped)
 

hi guys, i start a new thread because in the previous one i've made a mistake in the solver.
the correct error that i encounter is this. it happens both in serial and in parallel running.
could you help me?

>>>serial running error (entire ):

No MRF models present

No finite volume options present
