# OS-E: 0130 Plate with Central Hole using NLOUT

A uniform, homogeneous plate which is symmetric about horizontal axes in both geometry and loading, to find the maximum axial stress in the plate with a hole.

## Model Description

**FE Model**- Element Types
- CHEXA

**MAT1 and MATS1**- Youngâ€™s Modulus
- 1.5E5 MPa
- Poisson's Ratio
- 0.3
- Initial Yield Point
- 60.5 MPa

## Results

Nonlinear iterations do not converge and OptiStruct saves the last converged solution by default with NLOUT.

`SVNONCNV`parameter on NLOUT entry is set to YES by default:

- SVNONCNV = YES
- Saves the last non-converged iteration

`NON-CONVERGENT`at the final load factor, shown in Figure 2.
