What is a Convergence plot in solidworks?

What does a convergence graph show?

Convergence Plots. Convergence plots use graphics to show how an error estimate or time step evolves during the solution process for nonlinear, time dependent, and parametric solvers.

How do you make a convergence plot in Solidworks?

To generate convergence graphs:

1. Run a static study using the p-adaptive method.
2. Right-click the results folder and select Define Adaptive Convergence Graph.
3. In the PropertyManager, select the components that you want to graph and click .

What is simulation convergence?

When a simulation has generated enough statistics such as that the error estimate on the quantity you want to calculate is lower than the precision that is necessary for addressing your specific scientific question, then the simulation has converged.

What does a convergent graph look like?

If we look at a convergent sequence on a 2-D graph, it looks like a function with a horizontal asymptote. The dots will get closer and closer to height L as n gets bigger.

What does convergence mean?

Definition of convergence



1 : the act of converging and especially moving toward union or uniformity the convergence of the three rivers especially : coordinated movement of the two eyes so that the image of a single point is formed on corresponding retinal areas. 2 : the state or property of being convergent.

What is mesh convergence?

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 I refine mesh in Solidworks?

Refine the mesh overall to produce better aspect ratios by moving the mesh slider towards the ‘fine’ side. Locally refine the mesh by right clicking on ‘mesh’ in the tree and applying a mesh control to specific entities.

What is convergence of a function?

convergence, in mathematics, property (exhibited by certain infinite series and functions) of approaching a limit more and more closely as an argument (variable) of the function increases or decreases or as the number of terms of the series increases.

How do you do a convergence study?

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 tell if a graph is converging or diverging?

convergeIf a series has a limit, and the limit exists, the series converges. divergentIf a series does not have a limit, or the limit is infinity, then the series is divergent.

What are the convergence requirements?

Convergence Criteria

• Polynomial should be a complete polynomial i.e it must contain all the degree from 0 to the highest order of the derivative used in weak form. …
• The polynomial should be contineous over the element and also differentiable upto the order of the derivatives in the weak form.

Why is mesh convergence important?

The process of mesh convergence involves decreasing the element size and analysing the impact of this process on the accuracy of the solution. Typically, the smaller the mesh size, the more accurate the solution as the behavior of the design or product is better sampled across its physical domain.

What is convergence failure?

Iteration or convergence errors occur due to the difference between a fully converged solution of a finite number of grid points and a solution that has not fully achieved convergence.
