Hi,

I want to adapt my grid in fluent using grid adaption using the temperature profile. My simulation is done with a first order scheme.

My question is, should i converge the solution on a second order scheme before adapting the grid or is it ok to adapt from the first order solution??

Regards,

Eric

Usually the second order scheme gives more accurate results than the first order one, so also adaption should be better if based on a solution obtained with the 2nd order scheme.

I'd suggest, if possible (no unstable solution) and not too much time expensive, to obtain a converged solution with second order, then to adapt the grid, and let the solution converge again using second order discretization scheme.
