Hello,
I am writting my own solver. I encountered a problem when using adaptive mesh refinement. The error message indicated that it might be related to this line of code: volVectorField DUDt(fvc::DDt(phi_, Us_)); And I want to obtain the material derivative, is that right? Can someone kindly help me? Thank you. |

Try your solver in a simplest condition as possible. I mean no adaptive mesh in this case. If it works fine, then the problem is not from your solver. The adaptive mesh is tricky to use. Try it from coarse resolution and with only a few layers and steps of refinements.
