Adaptive meshing – Recoarsening

    • Johannes Menzel

      Hello,

      i am currently modelling a geometry free approach towards additive manufacturing. As part of it i am modelling the material deposition using the birth death scheme. Whenever a certain activation criteria (temperature, mass conservation) is met, a element is made alive contributing towards the solution. 

      With the possibilities of the model to predict the cross section of the deposited geometry, i am using a finer mesh.(see screenshot) While for thermal analysises the computational time is quite ok, it is taking 5x longer within the following static structural analysis. 

      I have read about adaptive meshing coarsening the mesh in regions where the temperature or some other variable gradient is below a certain value. I know Ansys is providing a mesh refinement scheme within the solution tab. Is it also able to coarsen the mesh adaptively in regions where a fine mesh is no longer needed?

      BR

      Hello,

      I donot know of any mesh coarsening algorithm. Please see following thread for similar sort of discussion: Mesh coarsening algorithm on APDL (ansys.com)
