how to evaluate mesh quality in PLAXIS 2D

 To evaluate mesh quality in PLAXIS 2D, follow these steps:

1. Mesh Generation:

   - In the Mesh Mode, you can generate a 2D mesh and inspect the generated Finite Element mesh.

   - The mesh generation process involves setting a global coarseness, which defines the average element size based on the model dimensions.

   - You can also locally refine the mesh by setting a local coarseness factor, which allows for better approximation of structural forces.

2. Mesh Inspection:

   - Once the mesh is generated, you can inspect it in the View Mesh option.

   - The output program will display the generated mesh, showing the finite elements as triangles.

   - You can evaluate the quality of the mesh by checking the shape of the elements. A good quality mesh should not have spiky or flat triangles, which can affect the accuracy of the calculation.

3. Mesh Quality Assessment:

   - PLAXIS 2D allows you to assess the mesh quality by evaluating the element aspect ratio for any element.

   - This helps in identifying and locating the worst quality shape elements, ensuring that the mesh is sufficiently fine for accurate results.

By following these steps, you can effectively evaluate and improve the mesh quality in PLAXIS 2D.
