Consolidation (FEM) Analysis

Finite Element Method is used to carry out Consolidation Analysis.

Load Steps and No. of Iterations

No. of Load Steps

Specify the number of increments for the defined load. If 1 is specified, the load will be applied all at once.

Maximum number of iterations per Load Step

Specify the maximum number of iterations for Analysis for each load increment.

Convergence Criteria

Specify the basis on which to assess the convergence in iterations. If multiple criteria are selected, all the criteria need to be satisfied to consider to have been converged.

Energy Norm

Assess the convergence on the basis of Energy (Unequilibrium  force x incremental displacement) Norm, which needs to be less than the specified value for convergence.

Displacement Norm

Assess the convergence on the basis of iterative incremental Displacement Norm, which needs to be smaller than the specified value for convergence.   

Unequilibrium Force Norm

Assess the convergence on the basis of Unequilibrium Force Norm, which needs to be smaller than the specified value for convergence.

 

 User Defined Time Step

Period

Total Analysis time.  

No. of Steps

Number of time steps the total Analysis time is divided into.  

Save Result

Check on to save Analysis results at each step, which can be checked from the Result Tree after completing the Analysis.

Log Scale

Save the time in the log scale.

Create Steps

The program generates steps.   

Total

The total sum must be equal to 1. The user directly defines the load steps.

 

Initial Water Level

Enter the underground water level condition. A function created by a basic function or the Water Level Function can be specified.
