Adoptation and error estimate

Please login with a confirmed email address before reporting spam

Hello dear, I am trying to model a high mach number flow and as a part of that I want to use adaptation and error estimates in the stationary solver for refinement of the mesh where it is needed, however I face with aproblem which I cannot understand. In "Adaptation and error estimates" section in "Stationary solver" I used "L2 norm of error squared" and for refinement method I used either "Longest" or "Regular", and for both of these choices I changed the "Element growth rate" from "1.7" to any number (Lower or Higher). But no matter I changed this number after solving and showing the refined mesh in the Mesh section, the element growth rate which used to refine is "1.7". I wonder why this number stay constant however I change it. Thanks in advance. Best regards, Saleh
