      hello, I'm running a simulation where involving fluid into the system, when I try to add methane and carbon monoxide, the ansys crash and force shut down

      Please can you explain how you're adding these materials? Ie multiphase, multispecies etc.

      I'm turn on Energy, Viscosity to Laminar , Species Transport to Species Transport (Volumetric) and SOFC with unresolved electrolyte addon module.

      In SOFC, there is a mixture I can add fluid into through the material option. I add Methane , CO and CO2. and Go to the mixture > Names> add the fluid and put N2 as last species. Then, the system crash once I try to apply

      OK, so you’re using a fuel cell module? That’s more likely to be causing your crash if used incorrectly. Don't you need O2 in the system?

      Yes fuel cell module

      I already add O2 in the system.

      The mixture contain H2, H2O, O2, CO , CO2 and CH4. Everything is fine until I put CH4. Why is that?

      I mean H2, H2O, O2, CO, CO2, N2 , and CH4. When I put CH4 as last species, it didn't crash but when I put above N2, it crash. I don't even use N2 actual

       The fl process could not be started.
       
       
      I tried using standalone fluent, this happen

      So it's more likely linked to the SOFC module than the species, or the species conflict with the module.

        I saw other paper using it. I don't know how.

      You may want to check the manual and tutorials then. It's not an easy function to use without some reading.

      A colleagues comment was to make sure you patch or initialise with species in the correct locations. If you rely on hybrid or initialise based on an inlet the solver may struggle.

      I can't even intialise the simulation because once I try adding methane, the software closed me down
