What is mesh convergence in Ansys?

Rouiba Convergence: Mesh convergence determines how many elements are required in a model to ensure that the results of an analysis are not affected by changing the size of the mesh. System response (stress, deformation) will converge to a repeatable solution with decreasing element size.

How do you do convergence analysis?

Solution:

1. Create a mesh using the fewest, reasonable number of elements and analyze the model.
2. Recreate the mesh with a denser element distribution, re-analyze it, and compare the results to those of the previous mesh.
3. Keep increasing the mesh density and re-analyzing the model until the results converge satisfactorily.

How do you change fluent convergence criteria?

To modify the convergence criterion for a particular variable, enter a new value in the corresponding convergence criterion field. If your problem requires the solution of many equations (e.g., turbulence quantities and multiple species), a plot that includes all residuals may be difficult to read.

How do I launch Ansys mechanical APDL?

Launch ANSYS Mechanical APDL: Click Start > All Programs > ANSYS 14.0 > ANSYS Mechanical APDL Product Launcher. In the resulting window, paste in the directory path in the Working Directory box: Click the Run button at the bottom of the window. The Mechanical APDL user interface will start. 3. Point to the results file identified in step 1:

How do I use the semi-implicit method in ANSYS mechanical?

One of the techniques we can utilize to get past this problem is the Semi-Implicit method in ANSYS Mechanical. As of 2019 R2, this needs to be activated using a Mechanical APDL command object, but it can be as simple as adding a single word within the Static Structural branch:

Is there a way to view damaged elements in ANSYS mechanical?

Fortunately we have access to the older ANSYS Mechanical APDL interface, which does allow us to select and visualize elements that have undergone too much distortion. This can be useful in that it tells us exactly where in the model the elements are failing.
