I'm using the Particle tracing and moving mesh modules to simulate particle accumulation due to settlement at flow channel boundaries. I add an "automatic remeshing" solver when solve the problem, it runs well at first, but once it remeshes, the error of "Undefined value found.
- Detail: Undefined value found in the stiffness matrix.
There are 1 equations giving NaN/Inf in the matrix rows for the variable comp1.fpt.Fvx.
There are 1 equations giving NaN/Inf in the matrix rows for the variable comp1.fpt.Fvy.
There are 328 equations giving NaN/Inf in the matrix rows for the variable comp1.qx.
There are 328 equations giving NaN/Inf in the matrix rows for the variable comp1.qy.
and similarly for the degrees of freedom, NaN/Inf in the matrix columns." occurs.
Does anyone know why this happens? Thank you very much for your help.
