Problem of parametric calculation with workbench

Damien_Breizh · March 13, 2018, 10:46

Hi,
I simulate the alkaline electrolysis of water. First, I model (only) the species reaction with wall reaction (not eletrochemical reaction). I can launch the calculation from Fluent but from workbench it does not work. Indeed, it stays on "initialization" or "loading of solution data" (it may be not exactly that because I translated from french).
I tried to :
-Refine the mesh (orthoganal quality 0.6)
-Decrease the time-step size
Can you help me to find how perform simulation and parametric simulation workbench?
Cordialement

I fond the problem.. .
He was coming from the name of the ionic potassium specis I think.
I had 5 species
oh- - hydroxyl-
o2- - oxygène
h2- - hydrogène
k+ - ionic-potassium
h2o<l> - liquid water
I changed ionic-potassium by ionicpotassium and k+ by k and now it is working.
