probably due to the error in Meshing, i.e. two fluid zones are not joined

The message is lack of memory. "Malloc" is memory allocation. You need more memory. When the data set is filled during initialisation additional memory is needed and cannot be found. Add more memory or reduce the model size (or go 64bit etc with more RAM as well)
