Hi, <\/p>\n
For modeling the electrochemical processes involved in water electrolysis I need to impose the electrode gas generation rate as a function of electric current density on the electrode surface. 2-phase Euler-Euler model has been chosen for multiphase flow and the gas generation function, written in Named Expressions,<\/strong><\/span> is called in the mass source term of phase-2 in the cells adjacent to the electrodes. However the solution freezes after few itereations leading to the error:<\/p>\n Interestingly, any function in the mass source term leads to the same error and it has nothing to do with the electric potential solution; even a function of temperature, pressure or any other variable produces the same error. Only if the gas generation rate is taken as constant then the solution continues without any problem.<\/p>\n Could this problem be related to Expressions<\/strong>? Any thoughts on this will be really appreciated as nothing could resolve this so far. Thanks.<\/p>\n <\/p>\n","protected":false},"template":"","class_list":["post-377494","topic","type-topic","status-publish","hentry","topic-tag-multiphase_models-1","topic-tag-electric-potential-2","topic-tag-electrochemistry","topic-tag-electrolysis-1","topic-tag-euler-euler"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\tError at host: Internal error at line 2388 in file 'bc\\src\\profile.c'.
