Determining the Smallest Cell Size in the Mesh

    • moe9423


      Hope you are all doing well.

      I am doing a transient laminar analysis to simulate pulsatile blood flow

      My fluid domain is a 2d  rectangle with the following dimensions: 3.5 cm (length) & 3 mm (diameter) and the mesh is shown below.

      I am trying to calculate the time step size using the courant number that's why I need to determine the smallest cell size in my mesh.

      Using fluent I tried 'check' mesh and by taking the square root of min area or cubic root of min volume I get cell size equal to 0.0262 m and 7.829*e-3 m respectively  which in both cases sounds unreasonable given that my domain has a diameter of 3e-3.

      Does anyone know how can I determine the smallest cell size in my domain?

      Thank you in advance

      As it is 2d the volume will be made by reference depth. Default is one meter if you did not change it under reference values.

      This makes a lot of sense now.

      Thank you for your help I appreciate it.
