fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Subhasish Mitra

It is not clear what exactly you want to simulate. Is it bubble growth in electrode and subsequent detachment or bubble shape deformation while it is rising? Anyway, coupled level set VOF (CLSVOF) method of FLUENT is good to simulate any bubble hydrodynamics.

Issam Ksentini

We are looking for both detachment of bubbles AND its hydrodynamic characteristics of produced bubbles such as size and rise velocity

If you know your bubble size at time t=0, then it is easy to simulate the detachment and subsequent rise process using FLUENT. However, if you would like to simulate bubble growth on the electrode, it is not straightforward. Bubble growth rate kinetics must be separately coupled through a user defined function to FLUENT.
